Dear all postgresql developers,

I have tested postgres v11 against TCP Wrappers but it does not respond
to TCP wrappers port blocking.

May I suggest the community to have postgres to work with TCP wrappers.??
Its security will be better.

Regards,
Timmy

The last stable release of TCP Wrappers was a couple decades ago. It's
deprecated in RHEL7 and removed in RHEL8. I'm not a PG core member or
anything but rather doubt that's an area where the developers will want to
expend effort.

Cheers,
Steve

Yeah, why bother. Even ’native’ encryption/SSL in PG (were one to use it ‘natively’, as we do) is so good; adding yet another layer seems overkill…

Yeah. In a quick dig through the project archives, I can find exactly
one prior suggestion that we should do this, and that email is old
enough to drink:

/messages/by-id/v0313030fb141b1665de9@%5B137.78.218.94%5D

That doesn't bode well for the number of people who would use or care
about such a feature.

Agreed. tcp_wrappers predates the widespread availability of easy,
effective software firewalls. Back when services listened on 0.0.0.0 and if
you were lucky you had ipfwadm, tcp_wrappers made a lot of sense. Now it's
IMO a pointless layer of additional complexity that no longer serves a
purpose.
