I just ran into an issue on 9.5.13 after creating a new schema with a set of tables in them, that no accounts (including schema / table owners) can insert into a table with a fk relation. A snippet of the error output in log files is as follows and looks like it is permissions related to the parent table:____

Is the FK to a table in another schema?

Can we see the schema definitions for the affected tables?


__ __

“permission denied for schema <schemaname>",,,"SELECT 1 FROM ONLY <schemaname>.<tablename> x WHERE ""id"" OPERATOR(pg_catalog.=) $1 FOR KEY SHARE OF x",20____

The schema and tables are all owned by the same group role, and members of the owner role are also getting the error. So far, all users both owner and non-owner have been able to successfully execute the select statement used by trigger and get either a 1 back, or no rows when the correct id is entered. When run from the application, writes to this table are immediately after writes to the parent table so that the id can be returned for the child table writes. Writes to both parent/child tables are occurring with the same account. The following short snippet are a couple of the commands run by an account which is in the group role owning the database, schema and tables in question:____

__ __

<database>=# SELECT 1 FROM ONLY "<schema>"."<table>" x WHERE "id" OPERATOR(pg_catalog.=) 3 FOR____

KEY SHARE OF x;____

I’ve spent a bit of time searching on different sites trying to find pointers to this particular case and haven’t found any good ideas yet for next steps on troubleshooting or pointing at root cause. Any pointers to next steps would be appreciated.
