Is there something like Mssql GUID in PostgreSql database

[Dragan Matic <mlists@xxxxxxxxxxxxxx>]

We are currently migrating a database from Ms Sql server to PostgreSQL. 
So far replication was done using GUID (global unique identifier) fields 
which is MS extension. I am wondering if something similar exists in 
PostgreSQL?

Tnx in advance
