[Featureserver] featureserver and dynamic layers?

[Bud P. Bruegger]

Hello everyone,

I'm trying to understand whether feature server meets my needs.  I have
some data in PostGIS and would like to create some web client
interfaces (using OpenLayers) to access the data.  

For this, I'd like a combination of potentially complex queries to
select the features and CRUD functionality to create/modify/delete
features.  

I have understood (correctly so?) that featureserver allows to query by
a bbox and an simple attribute values.  Are more complex queries
something to integrate into featureserver or is it better to implement
some REST service separately that say outputs GeoJSON?

thanks in advance for any input
