sorry for the noise.
what you stats_lock_check_privileges about privilege is right.

database owner cannot do
"ANALYZE one.t;"
but it can do "ANALYZE;" to indirect analyzing one.t

which seems to be the expected behavior per
https://www.postgresql.org/docs/17/sql-analyze.html
<<
To analyze a table, one must ordinarily have the MAINTAIN privilege on
the table.
However, database owners are allowed to analyze all tables in their
databases, except shared catalogs.
