+% DATABASE_INVALID_ACCESS invalid database access string: %1
+This is logged when an attempt has been made to parse a database access string
+and the attempt ended in error.  The access string in question - which
+should be of the form 'keyword=value keyword=value...' is included in
+the message.
+
+% DATABASE_MYSQL_COMMIT committing to MySQL database
+The code has issued a commit call.  All outstanding transactions will be
+committed to the database.  Note that depending on the MySQL settings,
+the committal may not include a write to disk.
+
+% DATABASE_MYSQL_FATAL_ERROR Unrecoverable MySQL error occurred: %1 for <%2>, reason: %3 (error code: %4).
+An error message indicating that communication with the MySQL database server
+has been lost.  If automatic recovery has been enabled,  then the server will
+attempt to recover connectivity.  If not, then the server will exit with a
+non-zero exit code.  The cause of such an error is most likely a network issue
+or the MySQL server has gone down.
+
+% DATABASE_MYSQL_ROLLBACK rolling back MySQL database
+The code has issued a rollback call.  All outstanding transaction will
+be rolled back and not committed to the database.
+
+% DATABASE_MYSQL_START_TRANSACTION starting new MySQL transaction
+A debug message issued when a new MySQL transaction is being started.
+This message is typically not issued when inserting data into a
+single table because the server doesn't explicitly start
+transactions in this case. This message is issued when data is
+inserted into multiple tables with multiple INSERT statements
+and there may be a need to rollback the whole transaction if
+any of these INSERT statements fail.
+
+% DATABASE_PGSQL_COMMIT committing to PostgreSQL database
+The code has issued a commit call.  All outstanding transactions will be
+committed to the database.  Note that depending on the PostgreSQL settings,
+the committal may not include a write to disk.
+
+% DATABASE_PGSQL_CREATE_SAVEPOINT creating a new PostgreSQL savepoint: %1
+The code is issuing a call to create a savepoint within the current
+transaction.  Database modifications made up to this point will be preserved
+should a subsequent call to rollback to this savepoint occurs prior to the
+transaction being committed.
+
+% DATABASE_PGSQL_DEALLOC_ERROR An error occurred deallocating SQL statements while closing the PostgreSQL lease database: %1
+This is an error message issued when a DHCP server (either V4 or V6) experienced
+and error freeing database SQL resources as part of closing its connection to
+the PostgreSQL database.  The connection is closed as part of normal server
+shutdown.  This error is most likely a programmatic issue that is highly
+unlikely to occur or negatively impact server operation.
+
+% DATABASE_PGSQL_FATAL_ERROR Unrecoverable PostgreSQL error occurred: Statement: <%1>, reason: %2 (error code: %3).
+An error message indicating that communication with the PostgreSQL database server
+has been lost.  If automatic recovery has been enabled,  then the server will
+attempt to recover the connectivity.  If not, then the server will exit with a
+non-zero exit code.  The cause of such an error is most likely a network issue
+or the PostgreSQL server has gone down.
+
+% DATABASE_PGSQL_ROLLBACK rolling back PostgreSQL database
+The code has issued a rollback call.  All outstanding transaction will
+be rolled back and not committed to the database.
+
+% DATABASE_PGSQL_ROLLBACK_SAVEPOINT rolling back PostgreSQL database to savepoint: $1
+The code is issuing a call to rollback to the given savepoint.  Any database
+modifications that were made after the savepoint was created will be rolled back
+and not committed to the database.
+
+% DATABASE_PGSQL_START_TRANSACTION starting a new PostgreSQL transaction
+A debug message issued when a new PostgreSQL transaction is being started.
+This message is typically not issued when inserting data into a
+single table because the server doesn't explicitly start
+transactions in this case. This message is issued when data is
+inserted into multiple tables with multiple INSERT statements
+and there may be a need to rollback the whole transaction if
+any of these INSERT statements fail.
+
+% DATABASE_PGSQL_TCP_USER_TIMEOUT_UNSUPPORTED tcp_user_timeout is not supported in this PostgreSQL version
+This warning message is issued when a user has configured the tcp_user_timeout
+parameter in the connection to the PostgreSQL database but the installed database
+does not support this parameter. It is supported by the PostgreSQL version 12 or later.
+The parameter setting will be ignored.
+
+% DATABASE_TO_JSON_BOOLEAN_ERROR Internal logic error: invalid boolean value found in database connection parameters: %1=%2
+This error message is printed when conversion to JSON of the internal state is requested,
+but the connection string contains a boolean parameter with invalid value. It is a programming
+error. The software will continue operation, but the returned JSON data will be syntactically
+valid, but incomplete. The culprit parameter will not be converted.
+
+% DATABASE_TO_JSON_INTEGER_ERROR Internal logic error: invalid integer value found in database connection parameters: %1=%2
+This error message is printed when conversion to JSON of the internal state is requested,
+but the connection string contains the integer parameter with a wrong value. It is a programming
+error. The software will continue operation, but the returned JSON data will be syntactically
+valid, but incomplete. The culprit parameter will not be converted.
+
+% DATABASE_TO_JSON_UNKNOWN_TYPE_ERROR Internal logic error: unknown element found in database connection parameters: %1=%2
+This error message is printed when conversion to JSON of the internal state is requested,
+but the connection string contains unrecognized parameter. It is a programming error.
+The software will continue operation, but the returned JSON data will be syntactically
+valid, but incomplete. The unknown parameter will not be converted.
