<div class="WordSection1"><p class="MsoNormal"> <p class="MsoNormal">This message was posted in the pgsql-general and

whatis expected by next summer.<p class="MsoNormal"> <p class="MsoNormal">When I run this select statement on the
databaseserver it returns in under 1 second but it takes a minute to open some tabs using pgAmin III (1.16.1).<p

Ifwe could elimiate it from the listed schemas it would help.  Is this possible in pgAdmin III?<p class="MsoNormal"> <p
