No, it doesn't, and we'd pay a nonzero price for allowing that. Currently the executor doesn't have to care (much) about whether a tuple is on-disk or in-memory --- the individual datums look the same either way. Allowing them to be different would force a lot of format conversion steps that currently need not happen. regards, tom lane ---------------------------(end of broadcast)--------------------------- TIP 1: if posting/reading through Usenet, please send an appropriate subscribe-nomail command to [EMAIL PROTECTED] so that your message can get through to the mailing list cleanly
