[BUGS] ON COMMIT DROP unstable behaviour

I'm using PG 10, pgAdmin 4, and PGMaestro 17.8.0.1.

I have a function that creates a temp table marked ON COMMIT DROP. The function performs read-only ops on the DB apart from using the temp table.

I observed the temp table sometimes fails to drop when executing the function. I am able to query its contents. Multiple calls to the function simply increases the temp table's contents.

I narrowed it down to the following scenario:

1) Remove the ON COMMIT DROP

2) Compile

3) Execute "SELECT * FROM func(1)"... temp table visible as expected

4) Put back the ON COMMIT DROP

5) Compile

6) Execute... temp table visible and grows with each call to the function

It's a bit complex to provide the function and tables, but I will if needed.
