pg driver and specificType

[aidenbell]

When using pg driver, table.specificType causes a crash building the table with:

{ '0': [TypeError: Property 'typeSpecific' of object # is not a function] }

The call was:

t.specificType('geom', 'GEOMETRY(Point, 26910)');

Issue seems to be:

https://github.com/tgriesser/knex/blob/3c8d08a64b3014cad237baec0f9cb023cb66bd73/lib/schemabuilder.js#L262

String 'specific' should be 'specificType'.

Running:

t._addColumn('specificType', 'geom', {
            specific: 'GEOMETRY(Point, 26910)'
        });

Manually adds the correct column.
