SQL commands not supported in ADB
Though Arenadata DB is based on PostgreSQL, some SQL commands and operators are not supported in ADB. This is due to the features of distributed databases. Below is a list of SQL commands that are currently missing in ADB (as well as in Greenplum).
NOTE
For more information on all SQL commands (including supported ones), see the Greenplum documentation.
