Created Unassigned: Issue with encoding of Chinook_PostgreSql.sql [29384]

I think the following header:
```
SET client_encoding = 'WIN1252';
```
should be added on top of Chinook_PostgreSql.sql since it actually use that encoding, but the default for psql is UTF8 nowadays, no matter the encoding of the target DB.

So, if you type
```
psql -f Chinook_PostgreSql.sql TestDb

```
you'll end up receiving a lot of errors:
```
psql:Chinook_PostgreSql.sql:237: ERROR: invalid byte sequence for encoding "UTF8": 0xf4 0x6e 0x69 0x6f
```
