删除同义词：
set pagesize 0
set feed off spool /home/oracle/dropsyn.sql select 'drop public synonym "' || synonym_name || '";' from dba_synonyms where table_owner='MDSYS'; spool off; @/home/oracle/dropsyn.sql在cdb和pdb都执行删除。种子PDB$SEED也要删组件，否则报错：
Database option SDO mismatch: PDB installed version 19.0.0.0.0. CDB installed version NULL.
SQL> alter session set "_oracle_script"=true;
Session altered.
SQL> alter pluggable database pdb$seed close immediate;
Pluggable database altered.
SQL> alter pluggable database pdb$seed open;
Spatial also creates a few user schemas during installation which can be dropped as well:
drop user mddata cascade;
select message from PDB_PLUG_IN_VIOLATIONS;
