LucaCappelletti94 opened a new pull request, #2668: URL: https://github.com/apache/datafusion-sqlparser-rs/pull/2668
PostgreSQL does not accept a single-quoted string as a column or table alias. The `SELECT` reference defines both as identifiers (https://www.postgresql.org/docs/current/sql-select.html), and PostgreSQL 16 rejects `SELECT 1 AS 'x'`, `SELECT 1 'x'`, `SELECT a FROM t AS 'y'` and `SELECT a FROM t 'y'` with a syntax error. The parser accepted a string alias in every dialect. A new dialect method, `supports_string_literal_alias`, defaults to `true` so the other dialects are unchanged, and `PostgreSqlDialect` sets it to `false`. Tests check the exact errors for column and table aliases in PostgreSQL and that every other dialect still accepts both. -- This is an automated message from the Apache Git Service.
