pgsql: Use true / false instead of 1 / 0 for bool parameters

Changes done with Coccinelle:

    @r1@
    identifier F;
    identifier p;
    typedef bool;
    parameter list [n1] PL1;
    parameter list [n2] PL2;
    @@

    F(PL1, bool p, PL2) {
    ...
    }

    @r2@
    identifier r1.F;
    expression list [r1.n1] EL1;
    expression list [r1.n2] EL2;
    @@

    F(EL1,
    (
    - 1
    + true
    |
    - 0
    + false
    )
    , EL2)
