   <!--Thanks very much for contributing to Apache DolphinScheduler. Please

   ## Purpose of the pull request
   
   <!--(For example: This pull request adds checkstyle plugin).-->
   
   Fix the problems of the sql upgradation script in 3.2.0 schema.
   This closes #13515
   
   ## Brief change log
   
   <!--*(for example:)*
   - *Add maven-checkstyle-plugin to root pom.xml*
   -->
   
   modify `dolphinscheduler_postgresql.sql` in `3.2.0_schema` directory, the 
brief change is as follow:
   
   - fix error syntax and use simpler syntax to add fields instead of defining 
functions
   - add column's comment;
   - remove the `DROP` script SQL. It is very dangerous to  drop tables or drop 
columns in an upgradation script, because it may cause data loss in an existing 
database;
   - add `t_ds_fav_task.task_name`'s  upgradation sql.  #12277
   
   ## Verify this pull request
   
   - create DS database using `3.1.x` schema.
   - upgrade DB:execute `dolphinscheduler_postgresql.sql` in `3.2.0_schema` 
directory;
   - Use the upgraded database to run version 3.2.0 DS.
   
   I have upgraded the DB from 3.1.4 schema to  3.2.0 schema, created the 
process, and ran the process to verify.
