Subject: Remove some dead IsUnderPostmaster code in bootstrap.c.
X-Git-Url: http://git.postgresql.org/gitweb/?a=commitdiff_plain;h=HEAD;p=users%2Fandresfreund%2Fpostgres.git

Remove some dead IsUnderPostmaster code in bootstrap.c.

Since commit 626eb021988a2 has introduced the auxiliary process
infrastructure bootstrap_signals() was never used when forked from
postmaster.

Remove the IsUnderPostmaster specific code, and add a appropriate
assertion.
