ompgsql: In case of PG not available lets retry instead of dropping messages.

Messages are lost in case of temporary PG operation errors, since RS_RET_SUSPENDED not propagated outside.

Possibly related to #1105

This looks like a flake, I have re-initiated the run. I'll also enable the rest of the CI now. Note that there are some timing-related flakes. I'll watch out for them. If you see somthing not related to your patch, no need to worry (I'll take care).

Note that I am currently busy with other work and can probably not babysit CI until next week.
