Hi! Other (besides text literal from my previous message) condition when we have ERROR: failed to find conversion function from "unknown" to .. is usage of null. When I invoke select 1 where 5 in (null) everything is Ok, though when I try select 1 where 5 in (select null) I get ERROR: failed to find conversion function from "unknown" to integer. Is it desired behavior or subject to change in future versions of PG? Thanks. -- Best regards Ilja Golshtein ---------------------------(end of broadcast)--------------------------- TIP 7: don't forget to increase your free space map settings
