Problem

• The PgSpannerSample.java code catches an ExecutionException and attempts to cast its cause directly to a SpannerException.
• The cause is actually a com.google.api.gax.rpc.FailedPreconditionException, resulting in a ClassCastException.
• This causes the java8-samples test to fail.

Solution

• Use SpannerExceptionFactory.asSpannerException(e.getCause()) to correctly convert or wrap the GAX exception into a SpannerException instead of casting directly.

Code Review

This pull request updates several database administration methods in PgSpannerSample.java to safely handle ExecutionException. Instead of directly casting e.getCause() to SpannerException, which could lead to a ClassCastException if the cause is of a different type, the code now utilizes SpannerExceptionFactory.asSpannerException(e.getCause()) to perform a safe conversion. There are no review comments, so I have no additional feedback to provide.

Code Review

This pull request updates PgSpannerSample.java to replace direct casting of e.getCause() to SpannerException with SpannerExceptionFactory.asSpannerException(e.getCause()) across multiple database administration methods. This prevents potential ClassCastException issues if the cause of the ExecutionException is not a SpannerException. There are no review comments to address, and I have no additional feedback to provide.
