Hi PG experts,
During next year, I've the goal to migrate an instance of 4 databases from PostGreSql 9.5 to 12 or maybe more 14.
What's the best tools I've to use ? Do a simple pg_dumpall in text format can archive this goal ?
What other files more than pg_hba.conf and postgresql.conf do I need to checK ?
And what issues can I find during this upgrade ?
