Description

It seems that the option "Use estimated data" in pg connection is ignored.
Qgis always use st_extent instead() of st_estimated_extent() when a new layer is loaded from PG.
It worked fine in 2.6.
Tested on 2.8 and 2.10

History

#1 Updated by Jürgen Fischer over 9 years ago

Are there stats for the tables in question (see pg_stats)? QGIS only uses st_estimated_extent on analyzed tables.

#2 Updated by Luca Lanteri over 9 years ago

I've done some other tests. The problem seems to be that I use INHERITS table. Pg_stats is correctly used for the child table but when I load the data from parent table they're ignored.

This is not a bug in QGIS but in POstGIS, hopefully fixed upstream:
