I chatted with Bruce Momjian about this a bit, too. My idea: PostgreSQL should provide functions that do this sort of thing, so that psql, DBD::Pg, org.postgresql.jdbc, and PostgreSQL ODBC can just use the functions without worrying about the version numbers.I received the following communication from Tom Lane, who is active in PostgreSQL development:... without so much as a "ta-ta" in the release notes. Hmph. Well, is
there any hope that a search-and-replace will convert old source code to
using the new table?
It shouldn't be a difficult change. Be aware that pg_constraint has more stuff in it than pg_relcheck did, so you'll want to add "WHERE contype = 'c'" to be sure you only see the rows corresponding to the old pg_relcheck table.
But then, somebody's gotta write the functions, contributed them to the project, get them committed, and then wait for 7.4 to take advantage of them. Still, it could eventually make such driver metadata requirements much more portable across later PostgreSQL versions.
