## Description of the issue
When PostgreSQL version 15 or greater is used, the `bench new-site` command files with insufficient permission error from PostgreSQL. This is due to the change introduced, where `PostgreSQL 15 also revokes the CREATE permission from all users except a database owner from the public (or default) schema.`

## Context information (for bug reports)

**Output of `bench version`**
```
5.19.0
```

## Steps to reproduce the issue

1. Configure Frappe to use PostgreSQL version which is 15 or greater (16.1 in my case)
2. Attempt to perform `bench new-site` (Ex: ERPNext)

### Observed result
Error from Postgres:
```
ERROR:  permission denied for schema public at character 14
```

Error from Frappe:
```
psql:/home/frappe/frappe-bench/apps/frappe/frappe/database/postgres/framework_postgres.sql:72: ERROR:  permission denied for schema public
```

### Expected result
Installation should proceed without any errors
