Support parser PostgreSQL

[Phạm Minh Đức <du...@toshiba-tsdv.com>]

Dear Dev Team's Apache Calcite,

I'm implementing Calcite for parsing PostgreSQL.

When parsing an SQL statement, having a config of SqlParser as :

SqlParser.Config sqlParserConfig = SqlParser./configBuilder/()

   .setParserFactory(SqlDdlParserImpl.*/FACTORY/*)

   .setConformance(SqlConformanceEnum.*/STRICT_2003/*)

   .setLex(Lex.*/ORACLE/*)

   .build();


On lastest version in Github, I see a test code on SqlParserTest to 
check syntax of PostgreSQL.

But I can not find lexical analysis for PostgreSQL.

It seem not support to check syntax of PostgreSQL and PL/pgSQL.

Could you please help me to confirm that ?

Currently, has Calcite support to parsing PostgreSQL Dialect ?

Thank you very much to your support.

Best Regards,

Pham Minh Duc.
