Doesn't do it here. And I wouldn't expect it to.
This was using the precise text of your example (with the corrected
funciton, which seems to contain an un-needed vSql variable, and with a
RAISE NOTICE line to make sure the function was called.).
It's possible you've found a bug, but more likely that there's something
unusual in your setup that you don't know about.
Two questions:
1. Are you running this actual test, on a newly created database?
2. Previously you said the following:

Are you saying the test you sent us doesn't behave the same on different
installations, or your actual application doesn't behave the same?
I'm guessing that you either:
1. Have a trigger you don't know about.
2. Have another function of the same name, but in a different schema
that is being called by mistake. Add a "RAISE NOTICE" to the function to
find out.
