ResultSetMetaData.getColumnDisplaySize() returns -1 for any column that
has an unknown size. Consider the REMARKS column of getTables(). This
data comes from the system's pg_description.description column which is of
type "text". There is no defined length for this, so we have decided to
return -1.

TABLE_CAT is generated by an untyped "SELECT NULL", we should probably
cast this to name, or report the currently connected database name here.
