Hackers, I discovered interesting issue with PostgreSQL transaction isolation. When transaction is in repeatable read isolation level, I can't see table which was created after transaction obtained snapshot. But I can run DML statements with this table. See example below.
Session 1 # begin transaction isolation level repeatable read; BEGIN # \dt No relations found. Session 2 # create table tmp (i int not null); CREATE TABLE # insert into tmp values (1); INSERT 0 1 # \dt No relations found. # select * from tmp; i --- (0 rows) # insert into tmp values (2); INSERT 0 1 # select * from tmp; i --- 2 (1 row) # commit; COMMIT Is it a bug? ------ Alexander Korotkov Postgres Professional: http://www.postgrespro.com The Russian Postgres Company
