[postgis-users] Raster Table Name With Upper-Case Characters

As a follow-up on this subject, I want to point out something 'strange' I
discovered with Rasters using mixed-case (lowercase and uppercase) in the
table names - QGIS takes like forever to load them. Whereas Rasters with
lowercase table names (that are loaded with the same parameters/options as
those with mixed-case table names using the raster2pgsql tool) load very
fast on QGIS.

Has anyone had similar experience? Can someone explain why this great
difference in performance between mixed-case and lowercase raster table
names and any possible workarounds. The preference for my project is
mixed-case raster table names.

*NB:* You need to test with a fairly large raster set to determine the
performance difference.
