Not so:

"If FILTER is specified, then only the input rows for which the
filter_clause evaluates to true are fed to the window function; other
rows are discarded. Only window functions that are aggregates accept a
FILTER clause."

(Per spec, FILTER appears only in the <aggregate function> production,
which is just one of the several options for <window function>.)
