Coverity complained about a defect in commit 257836a7: Calling "parsePGArray" without checking return value (as is done elsewhere 11 out of 13 times). Fix, and also check for empty strings explicitly (NULL as represented by PQgetvalue()). That worked correctly before only because parsePGArray() happens to set *nitems = 0 when it fails on an empty string. Also convert a sanity check assertion to an error to be more paranoid, and pgindent a nearby line. Reported-by: Michael Paquier <michael@paquier.xyz>
