|
The database server date/time when the transaction which modified the record started. This field will be the same as diag_timestamp_created for inserted records. General Usage This column is system maintained and should be considered read only in normal operations. |
|||||
| diag_wallclock_modified | timestamptz | 35,6 | clock_timestamp() |
|
|
The database server date/time at the moment the record was actually modified. For long running transactions this time may be significantly later than the value of diag_timestamp_modified. General Usage This column is system maintained and should be considered read only in normal operations. |

| diag_row_version | int8 | 19 | 1 |
|
|
The current version of the row. The value here indicates how many actual data changes have been made to the row. If an update of the row leaves all data fields the same, disregarding the updates to the diag_* columns, the row version is not updated, nor are any updates made to the other diag_* columns other than diag_update_count. General Usage This column is system maintained and should be considered read only in normal operations. Direct Usage This column is frequently used by by application logic to resolve the “dirty write” issues which can arise from concurrent data changes. As such any administrative override of automatic system maintenance of this value should consider the ramifications on application function. |
