Nice feature and qualifies for the next major release I think. looking ok overall, I would suggest trying to refactor, as much as you can, common code between the two modes. |

This pull request allows
PDO::pgsqlCopyFromArrayto acceptIterableinstead of justarray. This is not a breaking change since it still acceptsarray.The PostgreSQL
COPYstatement is a great interface. We can bulk insert a set of records by inputting them as CSV or TSV. PostgreSQL also supports processing them as a stream.However, the current
pgsqlCopyFromArraydoes not take full advantage of this capability. It requires that the records to be inserted be input as a single array, so it cannot be processed by piping external input to PostgreSQL'sCOPY.This weakness will be overcome by supporting not only simple arrays but also
TraversableandGenerator.
