Re: Strange code in initdb - Mailing list pgsql-hackers

I have modified these reports so they print the full path used.

Typical pg_dumpall output is:

    The program "pg_dump" is needed by pg_dumpall but was not found in the
    same directory as "/usr/local/postgres/bin/pg_dumpall".
    Check your installation.
