-# PostgreSQL JDBC driver
-
-[](https://travis-ci.org/pgjdbc/pgjdbc)
-
-This is a simple readme describing how to compile and use the Postgresql JDBC driver.
-
- - [Commit Message Guidelines](#commit)
-
-## Info
-
-This isn't a guide on how to use JDBC - for that refer to [Oracle's website](http://www.oracle.com/technetwork/java/javase/jdbc/) and the [JDBC tutorial](http://docs.oracle.com/javase/tutorial/jdbc/).
-
-For problems with this driver, refer to driver's [home page](http://jdbc.postgresql.org/) and associated [mailing list](http://archives.postgresql.org/pgsql-jdbc/).
-
-## Downloading pre-built drivers
-
-Most people do not need to compile PgJDBC. You can download prebuilt versions of the driver
-from the [Postgresql JDBC site](http://jdbc.postgresql.org/).
-
-## Compiling with Ant on the command line
-
-PgJDBC doesn't natively support compilation from IDEs like Eclipse, NetBeans or
-IntelliJ. You should compile with ant on the command line or create your own
-IDE project. Tips for use with some IDEs follow below.
-
-Before you can compile the driver you must download the source code from git.
-You cannot compile from a jar or a .zip distribution. Run:
-
- git clone https://github.com/pgjdbc/pgjdbc.git
-
-to download the source code. (You'll need git installed, of course).
-
-To compile you will need to have a Java 5 or newer JDK and will need to have
-Ant installed. To obtain Ant go to http://ant.apache.org/index.html and
-download the binary. Being pure Java it will run on virtually all Java
-platforms. If you have any problems please email the pgsql-jdbc list.
-
-Once you have Ant, simply run ant using 'ant -lib lib' in the top level directory.
-This will compile the correct driver for your JVM, and build a .jar file (Java ARchive)
-depending on the version of java and which release you have the jar will be named
-postgresql-.-.jdbc.jar. Where major,minor are the postgreSQL major,minor
-version numbers. release is the jdbc release number. N is the version of the JDBC API which
-corresponds to the version of Java used to compile the driver.
-
-*REMEMBER*: Once you have compiled the driver, it will work on ALL platforms
-that support that version of the API. You don't need to build it for each
-platform.
-
-## Creating a distribution zip
-
-To create a package of the driver jar, sources, and dependencies, run:
-
- ant dist
-
-## Dependencies
-
-PgJDBC has optional dependencies on other libraries for some features. These
-libraries must also be on your classpath if you wish to use those features; if
-they aren't, you'll get a PSQLException at runtime when you try to use features
-with missing libraries.
-
-Ant will download additional dependencies from the Internet (from Maven
-respositories) to satisfy build requirements. Whether or not you intend to use
-the optional features the libraries used to implement them *must* be present to
-compile the driver.
-
-Currently Waffle-JNA and its dependencies are required for SSPI authentication
-support (only supported on a JVM running on Windows). Unless you're on Windows
-and using SSPI you can leave them out when you install the driver.
-
-## Installing the driver
-
-To install the driver, the postgresql.jar file has to be in the classpath.
-When running standalone Java programs, use the `-cp` command line option,
-e.g.
-
- java -cp postgresql-9.4-1200.jdbc4.jar -jar myprogram.jar
-
-If you're using an application server or servlet container, follow the
-instructions for installing JDBC drivers for that server or container.
-
-For users of IDEs like Eclipse, NetBeans, etc, you should simply add the
-driver JAR like any other JAR to use it in your program. To use it within
-the IDE its self (for database browsing etc) you should follow the IDE
-specific documentation on how to install JDBC drivers.
-
-## Using the driver
-
-Java 6 and above do not need any special action to enable the driver - if it's
-on the classpath it is automatically detected and loaded by the JVM.
-
-For Java 1.5 and below, use `Class.forName` or a system parameter. See the main
-documentation and the JDBC tutorial for details - take a look at "more
-information" below.
-
-## JDBC URL syntax
-
-The driver recognises JDBC URLs of the form:
-
- jdbc:postgresql/
-
- jdbc:postgresql:database
-
- jdbc:postgresql://host/database
-
- jdbc:postgresql://host/
-
- jdbc:postgresql://host:port/database
-
- jdbc:postgresql://host:port/
-
-When the parameter `database` is omitted it defaults to the username.
-
-Also, you can supply both username and passwords as arguments, by appending
-them to the URL. e.g.:
-
- jdbc:postgresql:database?user=me
- jdbc:postgresql:database?user=me&password=mypass
-
-Notes:
-
-- If you are connecting to localhost or 127.0.0.1 you can leave it out of the
- URL. i.e.: `jdbc:postgresql://localhost/mydb` can be replaced with
- `jdbc:postgresql:mydb`
-
-- The port defaults to 5432 if it's left out.
-
-There are many options you can pass on the URL to control the driver's behaviour.
-See the full JDBC driver documentation for details.
-
-## More information
-
-For more information see the [the PgJDBC driver documentation](http://jdbc.postgresql.org/documentation/documentation.html) and [the JDBC tutorial](http://docs.oracle.com/javase/tutorial/jdbc/).
-
-## Bug reports, patches and development
-
-PgJDBC development is carried out on the [PgJDBC mailing list](https://jdbc.postgresql.org/community/mailinglist.html) and on [GitHub](https://github.com/pgjdbc/pgjdbc).
-
-### Bug reports
-
-For bug reports please post on pgsql-jdbc or add a GitHub issue. If you include
-additional unit tests demonstrating the issue, or self-contained runnable test
-case including SQL scripts etc that shows the problem, your report is likely to
-get more attention. Make sure you include appropriate details on your
-environment, like your JDK version, container/appserver if any, platform,
-PostgreSQL version, etc. Err on the site of excess detail if in doubt.
-
-### Bug fixes and new features
-
-If you've developed a patch you want to propose for inclusion in PgJDBC, feel
-free to send a GitHub pull request or post the patch on the PgJDBC mailing
-list. Make sure your patch includes additional unit tests demonstrating and
-testing any new features. In the case of bug fixes, where possible include a
-new unit test that failed before the fix and passes after it.
-
-For information on working with GitHub, see: http://help.github.com/articles/fork-a-repo and http://learn.github.com/p/intro.html.
-
-### Testing
-
-Remember to test proposed PgJDBC patches when running against older PostgreSQL
-versions where possible, not just against the PostgreSQL you use yourself.
-
-You also need to test your changes with older JDKs. PgJDBC must support JDK5
-("Java 1.5") and newer. Code that's JDBC4 specific
-may use JDK6 features, and code that's JDBC4.1 specific may use JDK7 features.
-Common code and JDBC3 code needs to stick to Java 1.5.
-
-Two different versions of PgJDBC can be built, the JDBC 3 and JDBC 4 drivers.
-The former may be built with JDK 5, while building JDBC4 requires JDK 6 or 7.
-The driver to build is auto-selected based on the JDK version used to run the
-build. The best way to test a proposed change with both the JDBC3 and JDBC4
-drivers is to build and test with both JDK5 and JDK6 or 7.
-
-You can get old JDK versions from the [Oracle Java Archive](http://www.oracle.com/technetwork/java/archive-139210.html).
-
-Typically you can test against an old JDK with:
-
- export JAVA_HOME=/path/to/jdk_1_5
- export PATH=$JAVA_HOME/bin:$JAVA_HOME/jre/bin:
- ant clean test
-
-For information about the unit tests and how to run them, see
- [org/postgresql/test/README](org/postgresql/test/README)
-
-### Ideas
-
-If you have ideas or proposed changes, please post on the mailing list or
-open a detailed, specific GitHub issue.
-
-Think about how the change would affect other users, what side effects it
-might have, how practical it is to implement, what implications it would
-have for standards compliance and security, etc. Include a detailed use-case
-description.
-
-Few of the PgJDBC developers have much spare time, so it's unlikely that your
-idea will be picked up and implemented for you. The best way to make sure a
-desired feature or improvement happens is to implement it yourself. The PgJDBC
-sources are reasonably clear and they're pure Java, so it's sometimes easier
-than you might expect.
-
-## Support for IDEs
-
-It's possible to debug and test PgJDBC with various IDEs, not just with ant on
-the command line. Projects aren't supplied, but it's easy to prepare them.
-
-### Eclipse
-
-On Eclipse Luna, to import PgJDBC as an Eclipse Java project with full
-support for on-demand compile, debugging, etc, you must:
-
-* Perform a git clone of PgJDBC on the command line
-* Use Ant to fetch the dependency JARs:
-
- ant -lib lib snapshot-version maven-dependencies
-
-* In Eclipse, File -> New -> Java Project
-* Uncheck "Use default location" and find your git clone of PgJDBC then
- press Next
-* Under Source, open "configure inclusion and exclusion filters"
-* Add the exclusion filters:
- `org/postgresql/jdbc3/Jdbc3*.java`
- `org/postgresql/jdbc3g/Jdbc3g*.java`
- ... and accept the dialog.
-
-* Under Libraries, choose Add JARs and add everything under `lib`
-* Click finish to create the project
-
-Note that unlike a JDBC4 JAR an Eclipse project will not be
-auto-detected using service discovery, so you'll have to use an
-explicit load:
-
- Class.forName("org.postgresql.Driver")
-
-Eclipse will interoperate fine with Ant, so you can test and debug
-with Eclipse then do dist builds with Ant.
-
-### Other IDEs
-
-Please submit build instructions for your preferred IDE.
-
-## Git Commit Guidelines
-
-We have very precise rules over how our git commit messages can be formatted. This leads to **more
-readable messages** that are easy to follow when looking through the **project history**. But also,
-we use the git commit messages to **generate the change log**.
-
-### Commit Message Format
-Each commit message consists of a **header**, a **body** and a **footer**. The header has a special
-format that includes a **type**, and a **subject**:
