I may be wrong but we in astronomy have several sky indexing schemes, which
allows to effectively use classical btree index. See

for details. Sergei Koposov has developed Q3C contrib module for
PostgreSQL 8.1+ and we use it with

Hi,
I have enabled the autovacuum daemon, but occasionally still get a
message telling me I need to run vacuum when I access a table in
pgadmin. Is this normal? Should I use scripts instead of the daemon?
Would posting config options make this a much more sensible question?

Hello,
Does anybody know how to build a database model to
include sizes for rings, tshirts, etc?
the current database is built like:
table product
=
productid int8 PK
productname charvar(255)
quantity int4
what i want now is that WHEN (not all products have
multiple sizes)
More detail please. It sounds like you running 8.1 and talking about
the integrated autovacuum is that correct? Also, what is the message
specifically from pgadmin?

pgAdmin notices a discrepancy between real rowcount and estimated
rowcount and thus suggests to run vacuum/analyze; it won't examine

Try contrib/btree_gist.
I've tried that one, but for my case it didn't help much.
The performance was almost equal or even slower than built-in btree.

contrib/btree_gist does nothing more than built-in btree - it's just
an support for multicolumn GiST indices.
