[postgis-users] design question: how to geocode multiple dynamic "city, country"?

[zach cruise]

i accept multiple "city, country" from users on-the-fly, and want to
dynamically map them.

i could create a table where i insert their multiple entries, and then
geocode that table for display.

but i also want to avoid giving write permission to the web user.

i could create a schema and restrict write to that schema.

or something better?
