Sequence last value is different among primary and secondary

[Kenny Bachman <kenny.bachman17@xxxxxxxxx>]

Hello Team,

I got a weird situation about the sequence value in PG 14.5 (rhel 8.6). The sequence's last value is different between primary and secondary nodes.

This sequence output belongs to the PRIMARY node:

SELECT * FROM "ACCOUNT_ITEM_SEQ" ;
 last_value | log_cnt | is_called
------------+---------+-----------
     105485 |      31 | t

This output belongs to the SECONDARY node:

SELECT * FROM "ACCOUNT_ITEM_SEQ" ;
 last_value | log_cnt | is_called
------------+---------+-----------
     105516 |       0 | t

There is no replication gap or lag between the nodes.

What is the reason behind this difference?

Thank you for your help and guidance in advance.

Will
