Does anyone know where I can request an OR-version of plainto_tsquery()?

plainto_tsquery expects plain text, use to_tsquery for boolean operators.

Are either of these definitions really right?  If I type "foo bar baz"
into Google, for instance, it seems to produce some sort of weighted
result, neither a strict AND nor a strict OR.  Google didn't get where
they are by misjudging what the simplest search behavior should be like.

we provide strict basic query language via to_tsquery(), which could be a foundation for different ql. We need consensus here and we leave it for future. Someone could write google like ql, but I didn't see any description what exactly google does. Currently, people write their own search wrappers which implement google-like ql.

      choose an index scan if your joining column's datatypes do not
      match
