how to get id of currently executed query?

hi,
i need something to distinguish two separate calls for some select.

i tried to use c functions GetCurrentTransactionId() and
GetCurrentCommandId(),
but there is a problem:
if i'll make plpgsql function, which uses GetCurrentTransactionId() and
GetCurrentCommandId() - getCurrentCommandId changes ( sql's from
functions also increment the command-id-counter).

so my question is - is there any way, to be able to tell "one query from
another"?

i would like to write a plpgsql function that would be able to
differentiate somehow it's calls from one statement to another.

i'm not sure if my description is correct - if you dont understand
something, please let me know.
