tolower() in odata query string produces LCASE() rather than LOWER() pg method

[KFoster-Marks]

When passing in the following:

$filter=contains(tolower(name), ${var})

the following is generated:

LCASE("name") like $1

which returns the following from the postgresql db:

ERROR: function lcase(character varying) does not exist

This package should generate the following, I believe:

LOWER("name") like $1
