sure. It is expected. Nobody can detect if "." inside name means part of
name or special symbol.
If you want to handle schema, you should to write some
format("SELECT * FROM %I.%I", schema_name, table_name);
For identifier separation, you can use "parse_ident" function
postgres=# SELECT parse_ident('a.b.cax."ass.ss"');
┌──────────────────┐
│ parse_ident │
╞══════════════════╡
│ {a,b,cax,ass.ss} │
└──────────────────┘
(1 row)
