Hi! I'm new to PostgreSQL (and C) and what I'm trying to do is to store a query plan on disc (in a binary file). My approach is to use SPI functions to get the query plan and then transform it into a 'storable' format (Replacing the pointers with actual values). Is there any other way to do this? Is my approach OK? The sure thing is that it is a messy task! I posted this message to the 'general' and 'novice' lists but the only answer I got was from the latter: " I'd look at extending the outfuncs/readfuncs code to deal with all the node types used in plan trees, andthen store text strings instead of binary. regards, tom lane", which seems a little confusing to me since as I said I'm a newbie. Thanks in advance, ntinoas
