Hi,
pgfdw_report_error() in postgres_fdw is implemented to report the message
"could not obtain ..." if message_primary is NULL as follows.
But, just before this ereport(), message_primary is set to
pchomp(PQerrorMessage()) if it's NULL. So ISTM that message_primary is
always not NULL in ereport() and the message "could not obtain ..." is
never reported. Is this a bug?
-------------------
if (message_primary == NULL)
message_primary = pchomp(PQerrorMessage(conn));
ereport(elevel,
(errcode(sqlstate),
message_primary ? errmsg_internal("%s", message_primary) :
errmsg("could not obtain message string for remote error"),
-------------------
If this is a bug, IMO the following change needs to be applied. Thought?
-------------------
ereport(elevel,
(errcode(sqlstate),
- message_primary ? errmsg_internal("%s", message_primary) :
+ (message_primary != NULL && message_primary[0] != '\0') ?
+ errmsg_internal("%s", message_primary) :
errmsg("could not obtain message string for remote error"),
-------------------
