in a test environment and then test the patch.

The behaviour you describe happens exactly when two processes e.g.
concurrently hold HANDLEs on the same file and one of those deletes
the file then. Windows keeps file names until all open HANDLEs are

If you see that somewhat frequently, use Process Monitor and Process

you to find all open handles per file. If it's not AV, it might be

Hello,
I've seen some situations where it would be very handy if PostgreSQL
could automatically prefix column names in a SELECT query with their
table names (or its alias). So for two tables, a & b, each with
columns "id" and "title":
SELECT * FROM a , b;
instead of returning ambiguou
Hello,
The manual says:

A column list cannot be specified when requesting transition relations.

Hello,
I am running into performance issues with large CTE "WITH" queries (just
for selecting, not updating). I was surprised to find that the queries
