Configuration parameter Tunables that to avoid

There are a few parameters in the postgesql.conf that have gathered up poor guidance in other guides you might come across, and they might already be set badly in a server whose configuration you're now responsible for. Others have names suggesting a use for the parameter that actually doesn't exist. This section warns you about the most common of those to avoid adjusting.

Some Parameter Tunable to avoid are:

• fsync
• full_page_writes
• commit_delay and commit_siblings
• max_prepared_transactions
• Query enable parameters
