Hi, ALL,
https://www.postgresql.org/docs/current/functions-admin.html#FUNCTIONS-ADVISORY-LOCKS

There is an explanation about a promissory
lock functions().

I have 2 questions about that:
1. Is calling one of them a way to get the lock()?
2. If I work on ODBC-based connection - I should call SQLExectDirect()
with the function in question, correct?

Thank you.
