Looks like it supports transactions:
[postgres@drow postgres]$ /usr/local/pgsql/bin/psql template1
Welcome to psql, the PostgreSQL interactive terminal.
Type: \copyright for distribution terms \h for help with SQL commands \? for help on internal slash commands
\g or terminate with semicolon to execute query \q to quit
template1=# begin;
BEGIN
template1=# create table intransaction (field1 int);
CREATE
template1=# rollback;
ROLLBACK
template1=# select * from intransaction;
ERROR: Relation 'intransaction' does not exist
template1=# begin;
BEGIN
template1=# create table intransaction (field1 int);
CREATE
template1=# commit;
COMMIT
template1=# select * from intransaction ;field1
--------
(0 rows)
template1=# begin;
BEGIN
template1=# drop table intransaction;
DROP
template1=# rollback;
ROLLBACK
template1=# select * from intransaction ;field1

(0 rows)
template1=# begin;
BEGIN
template1=# drop table intransaction;
