The code changes include the following:
1) Remove the max_size attribute as it is causing issues which are beyond the scope of this WL.
   The size of the tablespace increases during certain ALTER operations. Depending on the size of the table,
   this increase can be large making it difficult to estimate and enforce the max_size value for a table/tablespace.
   Removed the max_size attribute as enforcing it has deeper ramifications.
2) Bug fixes
   Bug#32018948: wrong error message when try to set autoextend_size of table created on general tblsp
   Bug#32025468: server crashes when autoextend_size change parallel to insert
