yjhjstz opened a new pull request, #1668:
URL: https://github.com/apache/cloudberry/pull/1668
The inconsistency between relpages=0 (from the wrong snapshot) and
num_tuples=56 (from the correct catalog snapshot) hits an assertion in
vac_update_relstats() that assumed this
combination — an AO table with zero pages but non-zero tuples — could only
occur in utility mode. Since the QE runs in GP_ROLE_EXECUTE, the assertion
Gp_role == GP_ROLE_UTILITY fails
and the segment process aborts.
Fix by passing NULL to GetAllAOCSFileSegInfo() so that systable_beginscan()
uses GetCatalogSnapshot() internally, consistent with
appendonly_relation_size() for AO row tables.
Fixes #ISSUE_Number
