Updated patch: I went through the "high traffic" areas and levelled them up to using the new macros to avoid "detoasting" smaller arguments. They key areas are really btree operators since they have a noticeable effect on sorts, especially index builds, when the data being sorted fits in memory.
There is a bit of a name-game here. The macros I made are called VARDATA_ANY(datum) VARSIZE_ANY(datum) AND VARSIZE_ANY_EXHDR(datum). And the datatype macros are, for example, PG_GETARG_TEXT_PP() and DatumGetTextPP() -- short for "packed pointer". Maybe not the prettiest names in the world but clear and I've found them pretty easy to spot when I'm looking for inconsistent use of VARSIZE_ANY<->VARDATA for example. I thought of PVARSIZE/PVARDATA (for "packed") but I'm afraid it would camouflage such cases. Anyone have any better ideas? If not I'm satisfied with them... Except maybe VARSIZE_ANY_EXHDR() which seems too long. I got to almost everything in varlena.c and varchar.c so that includes text, bpchar, and bytea as well as varchar's few procedures. That includes probably more than I really needed to, but as long as the datatypes are working with bytes it's convenient enough. Also, I replaced my tweaks to hstore and pg_trgm with Teodore's. And of course updated CVS. http://community.enterprisedb.com/varlena/varvarlena-20.patch.gz I'm going to be putting this aside for a little while. I think it's really done. There's more that can be done of course, hit inet and numeric with the new macros, for instance. But I want to see what happens when it gets reviewed before I do that kind of bookkeeping. One thing that I've left in there again is the htonl/ntohl macros in the big-endian case. It really makes sense to either remove them or remove the #ifdef. -- Gregory Stark EnterpriseDB http://www.enterprisedb.com ---------------------------(end of broadcast)--------------------------- TIP 5: don't forget to increase your free space map settings
