---------------------------------------
[~julianhyde] Ok, I will change the summary after I come up a way to express my
thoungt.
[~mbudiu] Hi, how to test following postgresql query in calcite:
{code:sql}
postgres=# select TIMESTAMP WITH TIME ZONE '1969-07-20 20:17:40 Asia/Shanghai';
1969-07-20 12:17:40+00
postgres=# select TIMESTAMP WITH TIME ZONE '1969-07-20 20:17:40';
1969-07-20 20:17:40+00
{code}
I think
https://github.com/apache/calcite/blob/main/core/src/main/java/org/apache/calcite/sql2rel/SqlNodeToRexConverterImpl.java#L130
and
https://github.com/apache/calcite/blob/main/core/src/main/java/org/apache/calcite/sql/parser/SqlParserUtil.java#L407
have some bugs.
