thanks steve.
if i use openlayers to do this, then i need lat/lon or get lat/lon via
ajax, as you said (openlayers would make it easier to add custom
pop-up text).
or i just select from a table of places.
Correct. You need a lat/lon to position the map so you have to get that
from your city names somehow.
If your table is places is reasonably small, you could just define it as
an array in Javascript and select from a dropdown list or search for the
name and then you would not make ajax requests.
Lots of ways to do this.

Zach,
You could do something like have a textarea where the user can enter a list
of cities and have a [Add] button, then in JS read the textarea, split the
text on linefeed into an array, the cycle through the array and make an ajax
request to geocode each city and add it to the map. Or you can just send the
whole textarea contents to the server and have it parse and geocode then
send back a geocode list like "city,x,y" and parse that in JS and add the
markers.

I sent the email below, then realized I can simply add custom dynamic
markers in openlayers on click (see
http://stackoverflow.com/questions/4624301/adding-custom-markers-dynamically-to-map-using-openlayers,
http://wiki.openstreetmap.org/wiki/OpenLayers_Marker_Example), but
need some real-life examples of how this could be done in batch.

Subject: design question: how to geocode multiple dynamic "city, country"?
To: PostGIS Users Discussion
Cc: PostgreSQL
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?
