-- Migration Doctor snapshot, SQL export: group names from all active directories (complete list; REST caps it).
-- Read-only: a single SELECT, no writes, no temporary tables. Output: one JSON object per line.
-- Run (read-only) with psql and save the output as groups.jsonl:
--   psql -X -q -A -t -v ON_ERROR_STOP=1 -h DBHOST -U READONLY_USER -d JIRADB -f groups.sql -o export/groups.jsonl
-- If the Jira tables are not in the default search_path, set PGOPTIONS='-c search_path=your_schema' first.
-- Then pass the export directory to the snapshot script: --sql-export-dir export (bash) or -SqlExportDir export (PowerShell).
