The current release of PG12 is 12.20, so you are missing fifteen minor
releases' worth of bug fixes, one of which might well have addressed
your problem. You should update to 12.20 before spending any further
effort on investigation.

Also ... PG12 will be out of support altogether after next month's
12.21 release. And I'm astonished that Red Hat would provide any
support whatsoever for RHEL7.4, which is about seven years obsolete
as well. You really need to make plans to migrate onto supported
versions sooner not later.
