That feature has only been built out in the other three PLs. Somebody oughta fix this sometime, I guess, but it evidently hasn't been high priority. If you feel like working on it, you could look at commits e5dc4cc24d2e1e94ac572a2c64103710bf15d21e (for plperl) and/or a5036ca998a6058f60913d43a80badfcbb65f5bb (for pltcl). regards, tom lane
