Easy enough to test:
create table test (a int, b text);
CREATE TABLE
smarlowe=# \z test
Access privileges
Schema | Name | Type | Access privileges | Column privileges | Policies
--------+------+-------+-------------------+-------------------+----------
public | test | table | |
grant select on test to stan;
GRANT
smarlowe=# \z test
Access privileges
Schema | Name | Type | Access privileges | Column privileges
| Policies
--------+------+-------+---------------------------+-------------------+----------
public | test | table | smarlowe=arwdDxt/smarlowe+| |
| | | stan=r/smarlowe | |
smarlowe=# drop table test;
DROP TABLE
smarlowe=# create table test (a int, b text);
CREATE TABLE
smarlowe=# \z test
Access privileges
Schema | Name | Type | Access privileges | Column privileges | Policies
--------+------+-------+-------------------+-------------------+----------
public | test | table | | |
So no, no phantom permissions.
