It is always rolled back. Its how plperl works today: create or replace function foo() returns int as $$ eval { spi_exec_query('create table uniq (num int primary key'); spi_exec_query('insert into uniq (num) values (1), (1);', 1); }; if($@) { # do something ... $@ == "duplicate key value violates unique constraint "uniq_pkey" at line 2." warn $@; } # oh well do something else # note the transaction is _not_ aborted spi_exec_query('select 1;', 1); return 1; $$ language plperl; =# begin; =# select foo(); =# select 1; =# commit; It does not matter if you use eval or not, its always in a sub transaction. > I see.
