I upgraded postgres to 6.5.3 with the same results
This is the error i get:
[14/Mar/2000:21:30:34][4964.5124][-conn1-] Error: Ns_PgExec: result status: 7
[14/Mar/2000:21:30:34][4964.5124][-conn1-] Error: nsd.tcl: Database operation "select" failed (exception NSDB, "Query was not a statement returning rows.")
Database operation "select" failed (exception NSDB, "Query was not a statement returning rows.")
while executing.........
The gethandle works ok and i have datasource, dbtype driver, poolname and user printed to a table.
It is not until set sql_query "select name, url, descr from links order by name" is executed that i get errors.
