Subject: enable CRC error detection for data pages by default
X-Git-Tag: auto/th/postgresql-9.3.5-1~1
X-Git-Url: https://git.pld-linux.org/?a=commitdiff_plain;ds=sidebyside;h=b8d42a8b7f4563906c6a235051a9750e688e2d1b;p=packages%2Fpostgresql.git

enable CRC error detection for data pages by default
this induces performance penalty, but if anyone blindly uses PLD init
script to create database, he will be better protected from silent data
corruption, while anyone familiar with PSQL can disable it on his own
