Tom Lane	266e771435	Fix entirely broken permissions test in new alter_operator regression test. Not only did this test fail to test what it was supposed to test, but it left a user definition lying around, which caused subsequent runs of the regression tests to fail.	2015-07-17 14:10:52 -04:00
Heikki Linnakangas	321eed5f0f	Add ALTER OPERATOR command, for changing selectivity estimator functions. Other options cannot be changed, as it's not totally clear if cached plans would need to be invalidated if one of the other options change. Selectivity estimator functions only change plan costs, not correctness of plans, so those should be safe. Original patch by Uriy Zhuravlev, heavily edited by me.	2015-07-14 18:17:55 +03:00

Fix entirely broken permissions test in new alter_operator regression test.

Not only did this test fail to test what it was supposed to test, but it
left a user definition lying around, which caused subsequent runs of the
regression tests to fail.

Add ALTER OPERATOR command, for changing selectivity estimator functions.

Other options cannot be changed, as it's not totally clear if cached plans
would need to be invalidated if one of the other options change. Selectivity
estimator functions only change plan costs, not correctness of plans, so
those should be safe.
