LibPQ logs but doesn't throw for nonexistent column names #211
Description
It seems that when getting a nonexistent column from a LibPQ.Row via getproperty, LibPQ logs a mysterious-looking error to stderr but doesn't otherwise indicate failure.
Should this be an exception?
Demo:
julia> conn = LibPQ.Connection("...");
julia> LibPQ.execute(conn, "create table test (a integer, b integer)")
julia> LibPQ.execute(conn, "insert into test values (1,2)")
julia> row = only(LibPQ.execute(conn, "select * from test"))
LibPQ.Row(PostgreSQL result, 1)
julia> row.a
1
julia> row.x
column number -1 is out of range 0..1
missingThe error column number -1 is out of range 0..1 is coming from inside upstream libpq:
