Hi All!
OS CentOS Linux release 7.7, PostgreSQL 14.17
timescaledb 2.15.3 apache license.
How do I downgrade to 2.15.1 Timescale License?
I’m trying to do
pgsqldb=# ALTER EXTENSION timescaledb UPDATE TO ‘2.15.1’;
ERROR: extension “timescaledb” has no update path from version “2.15.3” to version “2.15.1”
pgsqldb=# ALTER EXTENSION timescaledb UPDATE TO ‘2.15.2’;
ERROR: extension “timescaledb” has no update path from version “2.15.3” to version “2.15.2”
