Thread on pgadmin support:

Hello Dave,

This behavior (trying to show the entire geometry field) in Fedora
Core 6, pgAdmin3 1.6.2, doesn't happen...
In that scenario the geom field is simply shown blank.

Nevertheless, if I recall it correctly, proj4, geos, postgis versions,
in the above scenario, were older than the ones I'm using...
So I wonder... could it be that pgadmin's code changed for showing
large fields?
Could one of proj4, geos, postgis code changed that really interferes
with pgadmin3?

IMHO, regardless of the scenario involved, the output for large geom
fields should be suppressed in table edition... (as seen in the past)
The current behavior hogs way too much processor time.

I've tested with a micro-subset of my data (only one record with a
small parish geometry) and it shows although the slowness is
immediately apparent...

Kind regards,
Pedro Doria Meunier
