I feel the same about the second patch.

Although actually STATUS_WAITING is used only by ProcSleep and related
functions, likewise STATUS_EOF is seen only in auth.c/h. Other files,
pqcomm.c, crypt.c postmaster.c, hba.c, fe-auth.c , fe-connect.c,
fe-gssapi-common.c are using only STATUS_OK and ERROR. I haven't had a
close look but all of the usages would be equivalent to bool.

On the other hand many functions in fe-*.c and pqcomm.c returns
EOF(-1)/0 instead of STATUS_EOF(-2)/STATUS_OK(0).

We could reorganize the values and their usage but it doesn't seem to
be a big win..

regards.
