35608	Regression: many-to-many fields are not being correctly persisted to db from the admin	Adrian Capitanu		"**Prerequisites:**
- database: postgres16
- settings.py file that points to it
- have new connection pooling configured
- have a model that has a m2m field
- register that model to admin
- create a couple of instances to use in the m2m relationship

**Steps to repro:**
1. via admin, on a model with an m2m field, create a new model instance with no m2m relationships and save
2. edit the same instance, adding extra m2m relationships and save
3. re-open the same instance and observe m2m field

**Repro rate:**
- inconsistent
- maybe related to connection pooling?

**Expected result:**
The m2m field should have the options selected at (2) if the save was successful.

**Current result:**
The m2m field does not have some or all the options selected at (2), despite the save being successful.

**Affected Versions:** 5.1b1

**Working Versions:** 5.0.7"	Bug	closed	contrib.admin	5.1	Normal	needsinfo			Unreviewed	0	0	0	0	0	0
