This library contains a single PostgreSQL extension, a data type called "semver". It's an implementation of the version number format specified by the Semantic Versioning 2.0.0 Specification.
To build semver:
make
make install
make installcheck
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
Once semver is installed, you can add it to a database. If you're running PostgreSQL 9.1.0 or greater, it's a simple as connecting to a database as a super user and running:
CREATE EXTENSION semver;
If you've upgraded your cluster to PostgreSQL 9.1 and already had semver installed, you can upgrade it to a properly packaged extension with:
CREATE EXTENSION semver FROM unpackaged;
For versions of PostgreSQL less than 9.1.0, you'll need to run the installation script:
psql -d mydb -f /path/to/pgsql/share/contrib/semver.sql
If you want to install semver and all of its supporting objects into a
specific schema, use the PGOPTIONS environment variable to specify the
schema, like so:
PGOPTIONS=--search_path=extensions psql -d mydb -f semver.sql
The semver data type has no dependencies other than PostgreSQL and PL/pgSQL.
