Your architects are apparently completely unfamiliar with Postgres.
Tell them to read
https://www.postgresql.org/support/versioning/

particularly the bit about

While upgrading will always contain some level of risk, PostgreSQL
minor releases fix only frequently-encountered bugs, security issues,
and data corruption problems to reduce the risk associated with
upgrading. For minor releases, the community considers not upgrading
to be riskier than upgrading.

It is true that we've sometimes accidentally introduced regressions
into minor releases --- we're all mortal. But to focus on that case
and ignore all the genuine bug fixes in each minor release is flat out
folly.
