Rushabh Lathia of the EnterpriseDB development team and I have been
doing some testing of the extended query protocol and have found a
case where it causes an assertion failure. Here's how to reproduce:
1. Apply the attached patch to teach psql how to use the extended
query protocol. Compile, install.
2. Start the modified psql and do this:
\set PROTOCOL extended
PREPARE stmt as select 1;
CREATE TEMPORARY TABLE tmptbl AS EXECUTE stmt;
The result is:
TRAP: FailedAssertion("!(qry->commandType != CMD_UTILITY)", File:
"utility.c", Line: 1516)
