It was introduced about 6 years ago [1] and its purpose at the time is not clear.
Looking at that PR, I am also not sure. Maybe it was intended to be used for benchmarking? E.g., csv workload has a microbenchmarks that relies on InitialRows.

An `initial-` prefix is added to the payload column of the `bank`
table when the workload is initialized. It was introduced about 6
years ago [1] and its purpose at the time is not clear. There are two
main problems with it:
* the `initial-` prefix suggests the payload may be updated, but that
actually never happens.
* as currently implemented, it assumes that the `payload-bytes`
command line flag is at least `len([]byte("initial-"))`. Passing a
lower value to that command line flag leads to a panic. This is an
implicit assumption that should not exist.
This changes the row generation function so that `payload-bytes` bytes
are randomly generated and inserted into the `payload` column, without
the `initial-` prefix.
