I applied all patches and built/tested without any errors. So I guess
that the changes are correct.

I skimmed through 0001-0003 to see if I can find more parameters to
delete and found that we can remove the 'tinfo' parameter from the
gbt_var_node_truncate() function.

I do not have a context on this but there is a comment in the
citextcmp() function, which might be related to this context:

    /*
     * We must do our str_tolower calls with DEFAULT_COLLATION_OID, not the
     * input collation as you might expect.  This is so that the behavior of
     * citext's equality and hashing functions is not collation-dependent.  We
     * should change this once the core infrastructure is able to cope with
     * collation-dependent equality and hashing functions.
