Notes
1. You need to register related function points to use this data source. For details, see Registration Introduction.
2. The password that is used to access the database cannot contain the percent sign (%). Otherwise, the reindexing fails.
3. If a source table from a PolarDB PostgreSQL cluster contains fields of the DATETIME or TIMESTAMP format, the values of these fields are converted to the values in milliseconds. You must set the type of destination fields in your application to TIMESTAMP.
4. You cannot merge columns of source tables from different databases.
