Hi,
I tried to connect a db in PgAdmin III through pgpool-II (2.0.1) and got
a mismatch error log on
table pg_namespace and the PgAdmin failed connecting to that db. First,
I'm not sure why PgAdmin
wants to get info from that table to make the connection, second, I
don't know why that system table has
different rows in the backend hosts. Is there a way to let PgAdmin make
connection without checking
that system table, or a simple way to sync just that system table
between the backend hosts ?
Thanks,
Gary
