Tom, thanks again for the quick answer and sorry for the lame question about memor allocation.
I hope this is acceptable: Is there a way to make PG_DETOAST_DATUM and friends allocate memory in a custom memory context ? Right now I'm DETOASTing, memcopying in a custom context and pfreeing the DETOASTed datum, I'd like to avoid one copy. TIA. --strk; ---------------------------(end of broadcast)--------------------------- TIP 9: the planner will ignore your desire to choose an index scan if your joining column's datatypes do not match
