Nikolay and Michael discuss major and minor version Postgres upgrades — what they are, how often they come out, and how regularly we should be upgrading.
 
Here are links to a few things we mentioned: 

• Postgres versioning policy 
• why-upgrade (by depesz)
• postgresqlco.nf (by Ongres)
• postgresql.conf comparison (by Rustproof Labs) 
• pg_upgrade
• Logical replication 
• CHECKPOINT
• amcheck
• Locale data changes (e.g. glibc upgrades)
• ANALYZE
• Upgrades are hard (summary of panel discussion by Andreas 'ads' Scherbaum)
• spilo
• Recent pgsql hackers discussion about using logical and pg_upgrade together
