semver 0.2.0
============

This library contains a single PostgreSQL extension, a data type called
"semver". It's an implementation of the version number format specified by the
[Samantic Versioning Specification](http://semver.org/). Currently it's
implemented as a data domain, but may be converted to a native type
implemented in C in the future. Either way, functionality should remain the
same.

To build semver, just do this:

    make
    make installcheck
    make install

If you encounter an error such as:

    "Makefile", line 8: Need an operator

You need to use GNU make, which may well be installed on your system as
`gmake`:

    gmake
    gmake install
    gmake installcheck

If you encounter an error such as:

    make: pg_config: Command not found

Be sure that you have `pg_config` installed and in your path. If you used a
package management system such as RPM to install PostgreSQL, be sure that the
`-devel` package is also installed. If necessary tell the build process where
to find it:

    env PG_CONFIG=/path/to/pg_config make && make installcheck && make install

If you encounter an error such as:

    ERROR:  must be owner of database regression

You need to run the test suite using a super user, such as the default
"postgres" super user:

    make installcheck PGUSER=postgres

Dependencies
------------
The `semver` data type has no dependencies other than PostgreSQL and PL/pgSQL.
