[postgis-users] shp2pgsql creates spatial index *before* itinserts data? Is that right?

ANALYZE does make sense in some cases, when the statistical distribution
of values changes. VACUUM does not make sense on a freshly created and
populated table, only UPDATES and DELETEs cause VACUUMs to be needed.
CLUSTER and some ALTER TABLE commands also rewrite the table, making
VACUUM obsolete.

Btw, most recent PostgreSQL installations have Autovacuum running, so
the table will be vacuumed and analzyed as needed.
