There are still unrelated changes : spacing on -c and -t options' help. 
The "pgindent" command is passed on the sources from time to time, so 
there should be no reason to change this in this commit.

The updated string for PQerrorMessage does not bring much, and the message 
does not seem an improvement. "Command failed with ERROR", indeed.
  Command failed with ERROR:  syntax error at or near ";"  LINE 1: set synchronous_commit=on;set synchronous_;

The preceding result seems bother simpler and fine:
  ERROR:  syntax error at or near ";"  LINE 1: set synchronous_commit=on;set synchronous_;

Otherwise I've tested the patch with one "set", two "set"s and a syntax 
error, and it worked as expected.
