zabbix upgrade to 5.x, postgresql and timescaledb

[doum]

Hi,

we currently use zabbix 4.4.10, with postgres 10.12 and timescaleDb

In the upgrade notes I read :
Enabling extended range of numeric (float) values
Numeric (float) data type now supports precision of approximately 15 digits and range from approximately -1.79E+308 to 1.79E+308 (with exception of PostgreSQL 11 and earlier versions)

does it means that we don't have to do the numeric float values upgrade ? And if we don't have to do, do we have the problem regarding the timescaledb with too much chunk ? https://support.zabbix.com/browse/ZB...comment-430816
or this problem only happens on newer Postgresql that support extended range, but have an old timescaledb installation with chunks for 7 days instead of a month ?

nobody knows ?

There are a few things to consider:

1. make a backup strategy that cleans wall files that are no longer needed
2. move your db files out of /
3. check the global override housekeeping settings that come when using timescaledb. shareit
