Move the responsibility for caching specialized information about range types into the type cache, so that the catalog lookups only have to occur once per session. Rearrange APIs a bit so that fn_extra caching is actually effective in the GiST support code. (Use of OidFunctionCallN is bad enough for performance in itself, but it also prevents the function from exploiting fn_extra caching.) The range I/O functions are still not very bright about caching repeated lookups, but that seems like material for a separate patch. Also, avoid unnecessary use of memcpy to fetch/store the range type OID and flags, and don't use the full range_deserialize machinery when all we need to see is the flags value. Also fix API error in range_gist_penalty --- it was failing to set *penalty for any case involving an empty range. |
