Is there a reason we don't use pg_type.typcategory to detect arrays in
Postgres 8.4? Right now I see this in pg_dump.c:
if (g_fout->remoteVersion >= 80300)
{
appendPQExpBuffer(query, "SELECT tableoid, oid, typname, "
"typnamespace, "
"(%s typowner) AS rolname, "
"typinput::oid AS typinput, "
"typoutput::oid AS typoutput, typelem, typrelid, "
"CASE WHEN typrelid = 0 THEN ' '::\"char\" "
"ELSE (SELECT relkind FROM pg_class WHERE oid =
typrelid) END AS typrelkind, "
"typtype, typisdefined, "
"typname[0] = '_' AND typelem != 0 AND "
--> "(SELECT typarray FROM pg_type te WHERE oid = pg_type.typelem) = oid AS
isarray "
"FROM pg_type",
username_subquery);
}
It seems the appropriate 8.4+ test would be:
t.typtype = 'b' AND t.typcategory = 'A'
