 ### Using PostgreSQLClient in an AWS Lambda
 Because `psycopg` requires a statically linked version of the `libpq` library, the `PostgreSQLClient` cannot be installed as-is in an AWS Lambda function. Instead, it must be packaged as follows:
 ```bash
-pip install --target ./package nypl-py-utils[postgresql-client]==x.y.z
+pip install --target ./package nypl-py-utils[postgresql-client]==1.x.y
 
 pip install \
