Subject: modify the way PostgreSQL quotes backslashes
X-Git-Tag: plcapi-7.1-0~9
X-Git-Url: http://git.onelab.eu/?a=commitdiff_plain;h=5dc4edb45e7477a95ae7a7a3bb30662b9ba6bfff;p=plcapi.git

modify the way PostgreSQL quotes backslashes
this is for SFA and namely from fed4fire, who use
hrn's that have backslashes in them so as to
escape dots in hrns, when they are meant for FQDN-hostnames
