Обсуждение: pgsql: Adjust pg_regress to print out the exact string given to system()

Log Message:
-----------
Adjust pg_regress to print out the exact string given to system() when
'make install' or 'initdb' fails.  Also minor simplification of fgets()
usage --- fgets guarantees a trailing null anyway.
