Etsuro Fujita 5107398e6d postgres_fdw: Fix deparsing of remote column names in stats import. 
build_remattrmap() deparses a list of remote column names for a query
that retrieves attribute stats for them from the remote server.
Previously, it did so by using the array-literal syntax with each column
name individually quoted by quote_identifier(), causing the query to
fail on the remote server with a syntax error or no results when that
column name included a single quote or backslash, as quote_identifier()
doesn't escape those characters, making the query invalid or incorrect.
Fix by switching from the array-literal syntax to the ARRAY constructor
syntax with each column name individually quoted by
deparseStringLiteral().

Oversight in commit 28972b6fc.
