i have a problem. i need to create a have two tables in postgis (pgadmin). in one table there are points and in one table there are polygons(provinces). the tables are both over the same location (Netherlands). i want to count the points who are in every province and i want to export them to a row in the polygon (maybe a new table). so summarized i want from every province the points counted in a row.

my excuses for my terrible english.
