Hi @modosc,

Thank you for reporting this missing Aurora PostgreSQL version constant. You're correct that Aurora PostgreSQL 17.5 is supported by AWS RDS, but the corresponding AuroraPostgresEngineVersion.VER_17_5 constant is missing from the CDK library.

This is a straightforward addition that needs to be made to the AuroraPostgresEngineVersion class. The pattern is well-established, and we recently added VER_17_4 in a similar fashion.

Workaround: In the meantime, you can use the of() method to create the version:

const version17_5 = AuroraPostgresEngineVersion.of('17.5', '17', { s3Import: true, s3Export: true });

This is a great opportunity for a community contribution! The fix involves adding a single line to the AuroraPostgresEngineVersion class:

/** Version "17.5". /
public static readonly VER17_5 = AuroraPostgresEngineVersion.of('17.5', '17', { s3Import: true, s3Export: true });

Would you be interested in submitting a pull request for this addition? The change is straightforward and follows the existing pattern. You can find the file at packages/aws-cdk-lib/aws-rds/lib/cluster-engine.ts around line 1200.

Thanks for helping keep the CDK up-to-date with the latest AWS RDS versions!
