Bug reference:      17157
Logged by:          Lily Zhang
Email address:      bjzhangl@cn.ibm.com
PostgreSQL version: 13.3
Operating system:   os390x
Description:       

1. Since dict_int is trusted, we create extension of dict_int with normal
user. But when alter maxlen of intdict, it reports error. This is the
detail.
```
admin=> create extension dict_int;
CREATE EXTENSION
admin=> ALTER TEXT SEARCH DICTIONARY intdict (MAXLEN = 7);
ERROR:  must be owner of text search dictionary intdict
```
2. Since pg13 supports trusted extension, we make bloom trusted by changing
control file. Everything runs well except drop extension with normal user
who creates this extension.
```
test=> create extension bloom;
CREATE EXTENSION
test=> drop extension bloom;
ERROR:  must be superuser to drop access methods
```


Hi, here are some of my understanding, hope it can help you:

For (1), if we set an extension "trust", the database will execute the "create" action as a superuser, so the owner of the created object is the superuser. I think this is a "feature", not a "bug".

For (2), it was already been fixed in commit: b1d32d3e3230f00b5baba08f75b4f665c7d6dac6.
