MD5 would be 'char(34)' - MD5 produces a 32 character result, and
Postrgesql adds a 2 character tag.
https://www.postgresql.org/docs/current/static/pgcrypto.html
CLOB would be be 'text', or equivalently, 'varchar' without a length
qualifier. Postgresql does not distinguish character LOBs as a
separate type, and 'text' is just shorthand for unlimited 'varchar'.
https://www.postgresql.org/docs/current/static/datatype-character.html
I had to look up odcivarchar2list - according to the Oracle docs it is
a 'varray(m) of varchar(n)'.
The equivalent in Postgresql would be 'varchar(n)[m]'.

Hope this helps.
