I write this perl test case to reproduce problem, it needs both superuser and database name 'postgres'.
Also, I write the patch to fix that problem.
Thanks.

主题: BUG #17695: Failed Assert in logical replication snapbuild.
The following bug has been logged on the website:
Bug reference: 17695
Logged by: 施博文
Email address: zxwsbg@qq.com
PostgreSQL version: 14.6
Operating system: centos
Description:
In PG14 or higher version, I notice that SnapBuildRestore don't set
builder->next_phase_at=InvalidTransactionId .
But in SnapBuildSerialize function, the assert check this condition.
Assert(builder->next_phase_at == InvalidTransactionId);
This would cause some problems, and I have repeat it with the perl test case
which I would update later, the problem is following:
TRAP: FailedAssertion("builder->next_phase_at == InvalidTransactionId",
File: "snapbuild.c", Line: 1604, PID: 29974)
