DEBUG is for messages intended to help locating and analyzing faults in
the source code (i.e., debugging). Normal users don't need this during
normal operation.
INFO (or whatever the name) is for messages that administrator's might be
interested in for auditing and tuning.
Example:
elog(DEBUG, "heapgettup(..., b=0x%x, nkeys=%d, key=0x%x", buffer, nkeys, key);
vs.
elog(INFO, "connection: host=%s user=%s database=%s", ...);
There are maybe a dozen potential INFO messages, plus a few to be
converted fprintf's.
