error tryiing to insert with collate

Hi list,

Original collation srv+clis = fr_FR.utf8

I'm trying to insert as:
INSERT INTO tst1m VALUES ( default,
    'źŠÿǚŦÍÏÔJŽććżûŘäpèăîÍŢŃDµŴŻĊĜÿG' COLLATE "hu_HU.utf8",
    'úĽčŏṻŗĿÁťħĵŇğŚáÛĨæħŽīhĴÝUĶďeźİīŇč' COLLATE "hu_HU.utf8" );

and get: ERROR:  unsupported node type: 325

hu_HU.utf8 is installed - so is this operation impossible
and collate only reserved to select statements?
