I have some code which creates a function in Postgres, taken from http://wiki.postgresql.org/wiki/Array_agg . DROP AGGREGATE IF EXISTS array_agg(anyelement); CREATE AGGREGATE array_agg(anyelement) ( SFUNC=array_append, STYPE=anyarray, INITCOND='{}' ); The function was added in 8.4, and so the code fails when run on 8.4 or higher. How can I make the code cross-version compatible? For instance, how can I tell it to check the version, and only run if 8.3 or lower? Or another way to make it cross-version? -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
