Creation of new flag in RL8 fails

Running a command to create and publish to a new flag on an RL8 system (e.g., using the test suite to publish from segments-dev to segments-rl8) produces an error and fails.

Example: Running this: ligolw_segment_insert_dqsegdb --insert --segment-url=http://segments-rl8.ldas.cit --ifos=G1 --name=TEST_FLAG_GPS_TIME_1369765890 --version=1 -S /home/detchar/dqsegdb/known_segments_test_file.txt -G /home/detchar/dqsegdb/active_segments_test_file.txt --explain="This is a test flag published by test_segments_machine.sh on detchar-cit in a run started at GPS time 1369765890." --comment="This is a test flag published by test_segments_machine.sh on detchar-cit in a run started at GPS time 1369765890." Produces this message, which is normal: /usr/lib/python3.6/site-packages/dqsegdb/urifunctions.py:307: UserWarning: Info: Flag does not exist in database yet for URL: http://segments-rl8.ldas.cit/dq/G1/TEST_FLAG_GPS_TIME_1369765890/1, then several stack traces that end with the same error:

An example of this occurred at 11:35:55 PDT on 2023.06.02, attempting to publish the above flag, G1:TEST_FLAG_GPS_TIME_1369765890:1.

There are no particularly insightful messages in internal_access_log or internal_error_log on segments-rl8, but a Python server log (such as /opt/dqsegdb/python_server/logs/2023-06-02.log, for the example mentioned above) has this important line: 2023-06-02 11:35:55,746:CRITICAL:PUT /dq/G1/TEST_FLAG_GPS_TIME_1369765890 - Problem with ODBC statement execution (('HY000', "[HY000] [ma-3.1.12][10.3.35-MariaDB]Field 'dq_flag_assoc_versions' doesn't have a default value (1364) (SQLExecDirectW)"))
