X-Git-Tag: REL9_0_6~19 X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=c49130ade4dac5d8dff724cf15b0f0cdb9cf7d24;p=postgresql Throw nice error if server is too old to support psql's \ef or \sf command. Previously, you'd get "function pg_catalog.pg_get_functiondef(integer) does not exist", which is at best rather unprofessional-looking. Back-patch to 8.4 where \ef was introduced.
