pgsql: Since my name has a non-ascii-letter in it, it's often spelled

Log Message:
-----------
Since my name has a non-ascii-letter in it, it's often spelled wrong. In
the latest release notes there is a latin1 character that shouldn't be
there so I made a patch to fix that. This patch also fixes some old
entries that uses o instead of ö (which is also wrong but not as
bad as including a latin1 character in the sgml file).
