[GENERAL] FULL_PAGE_WRITES - Mailing list pgsql-general

Hi,

I am new to postgres, I have a simple question.

When this parameter FULL_PAGE_WRITES is set to ON, it writes the FULL pages to WAL, does it write just the data pages or both the index pages as well.

I tried running update statement on the table which updates the same number of rows with and without the index, the WAL size is the same.

Thanks,

Vishnu
