Hi,
FYI: I'd just like to point you to following two forthcoming standard
parts from "ISO/IEC JTS 1/SC 32" comittee: one on JSON, and one on
"Multi-Dimensional Arrays" (SQL/MDA).
They define there some things different as already in PG. See also

Nice work!
Just for completeness: Did you also think of including geometry types

There seems to exist some opportunities now with GIST which relate to

1. Index-only scans on geometry columns with SP-GIST (being able to do
a SELECT id FROM my_table WHERE mygeom...;).
2. Index clustering incuding NULL values (i.e. being able to do

Hi,
Unlogged tables seems to me to follow a similar goal. Obviously GiST
indexes are not supported there.
Do you know the technical reason?
Do you see some synergy in your work on fast GiST index building and
unlogged tables?

Hi,
We did a benchmark comparing a Key-Value-Pairs stored as EAV db schema
versus hstore. The results are promising in favor of hstore but there are some
question which remain.
1. Obviously the '@' has to be used in order to let use the GiST index.
Why is the '-' operator not supported by GiST
Ok.
But again: There is a library mentioned and documented in the famous
PostgreSQL book from Douglas Douglas called pgcurl (
http://gborg.postgresql.org/project/pgcurl/ ). Where's this gone?
