But does the test code you sent show this problem on:
1. all installations
2. some installations
3. none of the installations
4. Don't know - haven't tried the test code

If the test code shows the problem then we know it's something basic in
your PostgreSQL installations. If it doesn't then it's something in the
setup of the databases.

I don't think the problem has anything to do with the code of the
function. You have checked that the code in your functions makes sense
and looked at it on servers where it works and it doesn't. If the
problem was there I'm sure you'd have seen it.
