So b3f5ccebd promptly blew up on fairywren [1]:

connection error: 'psql: error: unterminated quoted string in connection info string'
while running 'psql -XAtq -d port=52984 host=C:/tools/nmsys64/tmp/hHg_pngw4z dbname='regression\\\\"\\\\

!"#$%&\\'()*+,-\\\\\\\\"\\\\\\\\\\\\' -f - -v ON_ERROR_STOP=1' at
C:/tools/nmsys64/home/pgrunner/bf/root/HEAD/pgsql/src/test/perl/PostgreSQL/Test/Cluster.pmline 2124. 

This shows that the command-line arguments to psql are not getting
adequately quoted on that platform.  AFAICS, we are relying on
IPC::Run::run to perform such quoting, and it seems to be
falling down here.  I wonder what version of IPC::Run fairywren
is using.
