Fix "Unable to identify an operator =$" problem that occurred when pgsql
expressions were written without spaces between operators and operands.Problem was that something like "if new.f1=new.f2 then" would be translatedto "if $1=$2 then", and the Postgres lexer would tokenize that the wrongway. Fix is to emit spaces around $paramno constructs to ensure they areseen as separate tokens.
