Re: pg_dump multi VALUES INSERT

Hello Surafel,

> okay .thank you for explaining. i attach a patch corrected as such

About this v9: applies cleanly, compiles, global and local "make check" 
ok.

The option is not exercise in the TAP tests. I'd suggest that it should be 
tested on a small table with zero, 1, more than the value set number of 
rows. Maybe use -t and other options to reduce the output to the minimum.

About the documentation:

  +   When using <option>--rows-per-insert</option>, this allows the maximum number
  +   of rows per <command>INSERT</command> statement to be specified.

I'd suggest a more direct and simple style, something like:

   Set the maximum number of rows per INSERT statement.
   This option implies --inserts.
   Default to 1.

About the help message, the new option expects an argument, but it does 
not show:

  +  printf(_("  --rows-per-insert    number of row per INSERT command\n"));

About the code, maybe avoid using an int as a bool, eg:

     ... && !dopt.dump_inserts_multiple)
  -> ... && dopt.dump_inserts_multiple == 0)

Spacing around operators, eg: "!=1)" -> "!= 1)"

ISTM that the "dump_inserts_multiple" field is useless, you can reuse 
"dump_inserts" instead, i.e. --inserts sets it to 1 *if zero*, and 
--rows-per-inserts=XXX sets it to XXX. That would simplify the code 
significantly.

ISTM that there are indentation issues, eg on added

   if (dopt->dump_inserts_multiple == 1) {

The old code is not indented properly.
