The problem here is that everyone has valid points.
Tom is quite correct that this sort of security policy really needs to
be implemented in a single central location, such as LDAP, AD or some
other IAM middleware. Having security policies implemented separately in
different systems is where failures creep in and why maintenance
becomes a problem.
Where Tom's solution fails is with smaller companies that cannot afford
this level of infrastructure. They can still fall victim to the same
level of regulatory bureaucracy, but without the necessary level of
technical resources of larger organisations. For these organisations,
basic facilities, like the ability to lock an account after a certain
number of failed login attempts for a period of time is a very useful
feature.
My suggestion would be to develop the basic requirements and contribute
the result to Postgres. This would give back to the community and
eliminate the need to maintain separate code in the long-term. The cost
of paying for extra resources to do this development and maintenance is
still going to be less than the licensing costs for that commercial
competitor. Just requesting the facility is unlikely to result in any
acceptable outcome within any reasonable time frame.
If your security people are really on top of their game, they will be
providing you with a security architecture which fulfils the enterprise
architecture requirements and which centralises IAM management. This is
really the only truly secure solution which guarantees access is removed
from all system in a timely manner, enables effective logging and
auditing of access, ensures consistent application of security policy
and allows consistent response to security incidents and events. While
requiring additional resources to establish, it does tend to result in
reduced maintenance costs in the longer term.
