Just encountered this error on an 8.1.2 cluster, wondering if
anyone can provide troubleshooting hints:
LOG: statement: PREPARE dbdpg_5 AS SELECT * FROM foo WHERE
visitnum = $1 and (scheduledtime >= $2 OR scheduledtime IS
NULL) AND (scheduledtime < $3 OR scheduledtime IS NULL) UNION
SELECT * FROM bar WHERE visitnum = $4 ORDER BY scheduledtime
LOG: statement: <BIND>
LOG: statement: EXECUTE <unnamed> [PREPARE: SELECT * FROM foo
WHERE visitnum = $1 and (scheduledtime >= $2 OR scheduledtime
IS NULL) AND (scheduledtime < $3 OR scheduledtime IS NULL)
UNION SELECT * FROM bar WHERE visitnum = $4 ORDER BY
scheduledtime]
ERROR: direct correlated subquery unsupported as initplan
A run of 'analyze' seems to have made the error go away.
Here's our version:
PostgreSQL 8.1.2 on ia64-unknown-linux-gnu, compiled by GCC gcc
(GCC) 3.4.3 20050227 (Red Hat 3.4.3-22.1)
Thanks,
