Just to be clear you tried the Control Panel method and that did not work?
I feel like it's related to Windows 11 as I never had trouble with SQL
uninstalls in Windows 10.

Aha! Thanks Tom! This will be my first time using valgrind, so I was unaware of
trace-children, and getting it to attach to forked stuff was exactly where I
thought the difficulty would lie.
This is great, much appreciated!
I’m suspecting that the leak might be coming from initStringInfo(),

You have to valgrind the whole cluster AFAIK. Basically, start
the postmaster under valgrind with --trace-ch
For membership/equality predicates (also partial, for multiple columns) you
could take a look at bloom indexes: they are quite efficient in terms of
space footprint, you can even choose how long is the signature for each
entry and how is distributed among the columns.

Hi,
I've got a background worker that has a slow memory leak in it
somewhere. How can I get it to start under valgrind to get a memcheck
output from it?
