Hi,
inpostgresql-8.1.3/src/backend/storage/lmgr/proc.c
there are 2 function InitProcess and
InitDummyProcess, both use
" if (MyProc != NULL) elog(ERROR,
"you already exist"); " (line 215 and 315)
why use " != " ?
Best regards.

I guess you misread exist to exit? Try
It done so, because InitProcess() is supposed to be called only
once per backend, because it allocates a PGPROC from a LIST OF free
PGPROCs.
So with this test, and calling elog( ERROR, ... ) we are stopping
the caller from doing a second initialization for this backend.

As Qingqing Zhou said, i misread exist.
Thanks.
