Is there a way to change the PostgreSQL password encryption method from MD5 to SHA?
If Yes, can you please tell me how?
I am using PostgreSQL 9.5

Pg 10
With PostgreSQL 10, you can set password_encryption
to scram-sha-256
. From the docs
When a password is specified in
CREATE ROLE
orALTER ROLE
without writing eitherENCRYPTED
orUNENCRYPTED
, this parameter determines whether the password is to be encrypted. The default value is md5, which stores the password as an MD5 hash. Setting this to plain stores it in plaintext. on and off are also accepted, as aliases for md5 and plain, respectively. Setting this parameter to scram-sha-256 will encrypt the password with SCRAM-SHA-256.
See this post for information about iterations using scram-sha-256
Pg 9.x
This can not be done without actually modifying the source.
