[xxjingcd]

Purpose of the pull request

Fix the problems of the sql upgradation script in 3.2.0 schema.
This closes #13515

Brief change log

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. [Improvement][DAO] the name of task_name of table t_ds_fav_task need to change #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.

About the delimiter syntax in pgsql

There is no delimiter syntax in pgsql function or storage procedure, and also no need for user to do that. For more, please refer to the discussion：Easy way of changing the delimiter in postgreSQL.
