Incompatibility
Fixing statistics with the following features may change the execution plan because the height of the Btree index is now fixed as well:
dbms_stats.lock_*
dbms_stats.restore_*
dbms_stats.import_*
Action method
If you want to run compatibility with Fujitsu Enterprise Postgres 15 SP2 and earlier, configure the following:
pg_dbms_stats.use_tree_height
pg_dbms_stats.lock_tree_height
