I'm a bit confused about how scan keys work. Is there any simple way given a list of Datums of the same type as the index tuple attributes to get all matching index entries? This is for a non-system index.
It seems like the only place in the code where non-system index lookups are done is nodeIndexscan.c where it has the strategy number, subtype, and function to use from the work that's previously been done on the expression. But I want to do something more like what btree does inside btinsert where it knows that no cross-type functions could be necessary and the only function of interest is equality. I tried just using index_getprocinfo(...,BTORDER) with InvalidStrategy like btree does but _bt_preprocess_keys runs into problems without a valid strategy number. And in any case that would be btree specific which seems like it ought not be necessary. -- greg ---------------------------(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
