Hi developers!
It would seem that pgAdmin4 pastes OID numbers as numeric literals instead
of string literals, if this report can be trusted:
https://dba.stackexchange.com/questions/247119/unable-to-output-data-from-tables-in-pgadmin-due-to-missing-oid-operator
Leads to sneaky errors with OIDs beyond 2^31. Details in the added answer
there. I did not recreate the issue as its hard to fake those OIDs.
Do you want me to add a bug report in Redmine?
Regards
Erwin
