Emit a log or error message. Possible levels are <literal>DEBUG</>,
<literal>NOTICE</>, <literal>ERROR</>, and <literal>FATAL</>.
<literal>DEBUG</> and <literal>NOTICE</> simply emit the given message
into the postmaster log (and send it to the client too, in the case of
<literal>NOTICE</>). <literal>ERROR</> raises an error condition:
further execution of the function is abandoned, and the current
transaction is aborted. <literal>FATAL</> aborts the transaction and
causes the current backend to shut down (there is probably no good
reason to use this error level in PL/Tcl functions, but it's provided
for completeness).

raises an error condition: further execution of the function is
abandoned, and the current transaction is aborted.
