[postgis-users] how to keep geometry_columns in sync with tables and views

[Ben Madin]

Ge,

Try 

    SELECT Populate_Geometry_Columns();

http://postgis.refractions.net/docs/Populate_Geometry_Columns.html

which promises to truncate the geometry columns table first, then rebuild it.

cheers

Ben

We have seen that under certain conditions (which are unclear) entries of the geometry_columns table are removed. So a mismatch occurs so now and then resulting in showing either no data or being very slow when an application has to do a table scan to obtain the geometry type.
