problem recovering pgsql 6.1 data - Mailing list pgsql-general

Hi!

I've got a major problem recovering the data, created by pgsql 6.1.  The
original binaries are lost.  And newly built (with CACHEDEBUG) one dump
core:

[akhavr@kbi akhavr]$ date; sudo -u postgres /home/akhavr/postgres \
-D /home/postgres/data -e -d 2 mailingad
Tue Dec 22 15:50:35 EET 1998
FindBackend: found "/home/akhavr/postgres" using argv[0]
    ---debug info---
    Quiet =        f
    Noversion =    f
    stable    =    f
    timings   =    f
    dates     =    European
    bufsize   =    64
    query echo =   f
    multiplexed backend? =  f
    DatabaseName = [mailingad]
    ----------------

    InitPostgres()..
