Description:

Hi,
at https://www.postgresql.org/docs/9.3/static/catalog-pg-class.html the 
"reloptions" column description is "Access-method-specific options, as
"keyword=value" strings". Maybe it should mention "Storage parameters" and
have a link to 
https://www.postgresql.org/docs/9.3/static/sql-createtable.html#SQL-CREATETABLE-STORAGE-PARAMETERS
?..
