With Postgres 8.4 query like SELECT * FROM core.tag_links ctl WHERE (ctl.tag_id = ANY ( SELECT array_agg(ct.id) FROM core.tags ct WHERE (LOWER(ct.tag) LIKE LOWER(('search tag')::text || '%') ESCAPE E'\\') ));
produces error: ERROR: operator does not exist: bigint = bigint[] ROW 3: WHERE (ctl.tag_id = ANY ( ^ HINT: No operator matches the given name and argument type(s). You might need to add explicit type casts. Bith ct.id and ctl.tag_id - of type BIGINT. Result of SELECT array_agg(ct.id) FROM core.tags ct WHERE (LOWER(ct.tag) LIKE LOWER(('search tag')::text || '%') ESCAPE E'\\'); array_agg ----------------------------------------------------------------------------------------------------------------------------- {54426,53600,54062,187207,187642,54395,53312,51912,128621,19203,6613,54462} (1 row) Should ANY (...) and ALL (...) work when "..." is a subquery, returning single ARRAY field, or maybe I misunderstood something?
