I used pg_get_viewdef() function to properly detect views and tables in
PgAccess.
For the moment, I have released a new version 0.94 of PgAccess based on
this and it works fine.

I am sure that you are right concerning pg_get_viewdef() function, but
please, could you tell me another way of detecting views from "false
views" ? relhasrules field isn't good enough for it and for the moment,
pg_get_viewdef() seems to be a good method. If anyone could tell me
another way of safely detecting views I can change it.

Also, I used pg_get_viewdef() in order to get views's definition for the
"Design" view function so, I will need also such a function in order to
implement this feature.
