continuing my quest for better testing ... ;-)
The current plperl regression tests do not test the trigger or shared
data features. The attached new files remedy that:
sql/plperl_trigger.sql
sql/plperl_shared.sql
expected/plperl_trigger.out
expected/plperl_shared.out
The corresponding patch for GNUmakefile is below
Is it worth supplying a more descriptive name to the current plperl.sql
test script?
cheers
