curly braces to group outer joins in queries from OpenOffice.org?

Hi!

I just tried using openoffice to create a SQL query, but it failed when I
tried using left outer joins. The contructed query from OO contains curly
braces to group things. I've never seen this construct before. Is it OO
doing bad things, or does postgresql not understand it? It's on pg-7.3.4.
Perhaps 7.4 behaves differently?

SELECT "personer"."foretag", "personer"."fnamn", "personer"."enamn",
"befattningnamn"."namn"
FROM { OJ "public"."befattning" "befattning"
LEFT OUTER JOIN "public"."personer" "personer" ON "befattning"."personid"
= "personer"."personid" },
"public"."kommentar" "kommentar", "public"."personer" "personer",
"public"."befattning" "befattning",
"public"."befattningnamn" "befattningnamn" WHERE 0 = 1

ERROR: parser: parse error at or near "{" at character 100

(The WHERE 0 = 1 seems to be OO's way of checking the query syntax.)

Thanks
