|
* A test program for libpq URI format

|
*
|
|
* This is a helper for libpq conninfo regression testing. It takes a single
|
|
* conninfo string as a parameter, parses it using PQconninfoParse, and then
|
|
* prints out the values from the parsed PQconninfoOption struct that differ
|
|
* from the defaults (obtained from PQconndefaults).
