I want to implement a multi-company database where each schema represents 
different company.

I created a number of schemas in a database.

How to select a list of schema names which current user is authorized to 
access ?

I want to get the list of companies to allow user pick the one.

See "System Catalogs" and "System Information Functions" (or
"Miscellaneous Functions") in the documentation.  Here are links
to documentation for the latest release:

http://www.postgresql.org/docs/8.0/interactive/catalogs.html
http://www.postgresql.org/docs/8.0/interactive/functions-info.html

Something like this might be what you're looking for:

SELECT nspname
FROM pg_namespace
WHERE has_schema_privilege(nspname, 'USAGE')
ORDER BY nspname;

Note that USAGE privilege on a schema doesn't necessarily mean the
user has any privileges on the objects in that schema.
