You can use statement-level logging, though there are no facilities in
statement-level logging to restrict what is logged to only one role's
activity.
You can use the usual audit triggers on database tables, which is what I
would recommend. Audit triggers in PostgreSQL cannot track reads
(SELECTs), only INSERT/UPDATE/DELETE and in 8.4 also TRUNCATE. They
cannot track ALTER/RENAME/DROP table, changes to sequences, etc. It is
trivial to write an audit trigger that only records anything when a user
is a member of a particular role.
