Commit Karel's patch.
------------------------------------------------------------------- Subject: Re: [PATCHES] encoding names From: Karel Zak <zakkr@zf.jcu.cz> To: Peter Eisentraut <peter_e@gmx.net> Cc: pgsql-patches <pgsql-patches@postgresql.org> Date: Fri, 31 Aug 2001 17:24:38 +0200 On Thu, Aug 30, 2001 at 01:30:40AM +0200, Peter Eisentraut wrote: > > - convert encoding 'name' to 'id' > > I thought we decided not to add functions returning "new" names until we > know exactly what the new names should be, and pending schema Ok, the patch not to add functions. > better > > ...(): encoding name too long Fixed. I found new bug in command/variable.c in parse_client_encoding(), nobody probably never see this error: if (pg_set_client_encoding(encoding)) { elog(ERROR, "Conversion between %s and %s is not supported", value, GetDatabaseEncodingName()); } because pg_set_client_encoding() returns -1 for error and 0 as true. It's fixed too. IMHO it can be apply.
