How do I get the Getting distance meter value between two geometries in PostGIS?

I have a simple question about calculating distances inam using PostGIS.

I would like to get the distance between two geometries. I am using this sid : 4269 in meters what i am doing now is this : ST_Distance((a.geom,b.geom)) FROM ... but I am getting result in degrees. 

I think that I should work with geography but how can I cast a geom to a geography? 

I tried with (a.geom::geography) but i am getting an error.

What can I do to get my result in meters?

Thank You
