BTW I'll "promote" this test to the EF test suite later as it's not very PG-specific.

{
await AssertQuery(ss => ss.Set<BasicTypesEntity>().Where(e => e.ByteArray.Any()));

AssertSql(
"""
SELECT b."Id", b."Bool", b."Byte", b."ByteArray", b."DateOnly", b."DateTime", b."DateTimeOffset", b."Decimal", b."Double", b."Enum", b."FlagsEnum", b."Float", b."Guid", b."Int", b."Long", b."Short", b."String", b."TimeOnly", b."TimeSpan"
FROM "BasicTypesEntities" AS b
WHERE length(b."ByteArray") > 0
""");
}

private void AssertSql(params string[] expected)
=> Fixture.TestSqlLoggerFactory.AssertBaseline(expected);
}
