autoinc
Make @receiver column an auto-increment column to generate its values in a database. Note: Only integer and long columns are supported (signed and unsigned types). Some databases, like PostgreSQL, support auto-increment via sequences. In this case a name should be provided using the idSeqName param and Exposed will create a sequence. If a sequence already exists in the database just use its name in idSeqName.
Parameters
idSeqName
an optional parameter to provide a sequence name
