The query I posted in another message appears to work in 7.4 and
later (i.e., versions that have the Information Schema):
SELECT character_value
FROM information_schema.sql_implementation_info
WHERE implementation_info_name = 'DBMS VERSION';
Unless I'm misreading what set_info_version() and setup_schema()
do in initdb.c, the above query will return a value based on the
value of PG_VERSION that was current when the initdb that initialized
the cluster was built. Although that raises a question: is that
the desired behavior, or should 'DBMS VERSION' return the version
currently running?
