SQL operator '*='

Hello,

I've here a smaller problem of our porting from Sybase/Oracle/Informix
code to PostgreSQL; the code reads for the mentioned DBS:

...
#ifdef DBSINF
EXEC SQL DECLARE land_cursor CURSOR FOR
SELECT stammprio, lkz, landbez, plkz, postbez, karenz1, karenz2,
karenz3, land.wkz, webez, we, kurs, land.del
FROM land, OUTER devisen
WHERE land.wkz = devisen.wkz AND land.brgroup = devisen.brgroup AND land.brgroup = :brgroupHost_for_helpland_cursor
ORDER BY stammprio, landbez;
#endif

#ifdef DBSORA
EXEC SQL DECLARE land_cursor CURSOR FOR
SELECT stammprio, lkz, landbez, plkz, postbez, karenz1, karenz2,
karenz3, land.wkz, webez, we, kurs, land.del
FROM land, devisen
WHERE land.wkz = devisen.wkz (+) AND land.brgroup = devisen.brgroup (+) AND land.brgroup = :brgroupHost_for_helpland_cursor
ORDER BY stammprio, landbez;
#endif

#ifdef DBSSYB
EXEC SQL DECLARE land_cursor CURSOR FOR
SELECT stammprio, lkz, landbez, plkz, postbez, karenz1, karenz2,
karenz3, land.wkz, webez, we, kurs, land.del
FROM land, devisen
WHERE land.wkz *= devisen.wkz AND land.brgroup *= devisen.brgroup AND land.brgroup = :brgroupHost_for_helpland_cursor
ORDER BY stammprio, landbez;
#endif

#ifdef DBSPOS
EXEC SQL DECLARE land_cursor CURSOR FOR
SELECT stammprio, lkz, landbez, plkz, postbez, karenz1, karenz2,
karenz3, land.wkz, webez, we, kurs, land.del
FROM land, devisen
WHERE land.wkz *= devisen.wkz AND land.brgroup *= devisen.brgroup AND land.brgroup = :brgroupHost_for_helpland_cursor
ORDER BY stammprio, landbez;
#endif

(the code for DBSPOS was just copied from Sybase). It compiles fine but
raises on execution en error about operator '*=' is not supported...

Any ideas about how to express this correctly in PostgreSQL?

Thanks

matthias
