Обсуждение: pgsql: Minor tweak to avoid unnecessary memory bloat when dumping

Log Message:
-----------
Minor tweak to avoid unnecessary memory bloat when dumping extremely wide
column values in -d mode.  Per report from Marty Scholes.  This doesn't
completely solve the issue, because we still need multiple copies of the
field value, but at least one copy can be got rid of painlessly ...
