Parameters:

• attempt=1
• race=true
• run=3
• shard=1

Jira issue: CRDB-68579

Inspect pkg/sql/sqlstats/sslocal/sql_stats_test.go around line 643 and review the captured logs from TestAssociatingStmtStatsWithTxnFingerprint. Reproduce the enabled=false failure with the race setting and determine why the expected count is 4 rather than 7. Done means the test reliably passes on release-26.3.
