description:
pgsql.buildlink3.mk is used to select a PostgreSQL version for use by
pkgsrc. It is modeled after lang/python/pyversion.mk and like it
could be influenced by user- and package-settable variables.

More precisely, tt's behaviour is controlled by the following
two variables:

- PGSQL_VERSION_DEFAULT
  A user-settable variable to choose the default PostgreSQL version.
  Default: 74

- PGSQL_VERSIONS_ACCEPTED
  A package-settable list of PostgreSQL versions accepted by the package.
  Default: 74 73

After postgresql-* has been reimported as postgresql73* all depending
packages should be changed to use mk/pgsql.buildlink3.mk.
