[charts] Default to two connections (main, and ci)
Default to two DB connections (main
, and ci
)
Proposal
Change flag for Chart from #4112 (closed) to default to true
If there is already an explicit configuration, we should respect that.
Documentation Update
This issue should also update the documentation regarding:
- What is changing in this release %16.0 with defaulting to two connections, as opposed to using one connection before.
- Intructions on how to switch back to one connection. Opposite of the existing documentation that has been done prior to %16.0 for the related platform.
- Intructions on how to instruct Omnibus/chart to keep using single connection before upgrading to %16.0 (aka pin)
Notes
- We deliberately make this change in a major version %16.0 because it is a big change.
- Customers can flip it back to false (e.g. if they encounter issues).
- Test two connections with internal postgresql
