Further experience says that the appending behavior offered by pg_get_line_append is useful to only a very small minority of callers. For most, the requirement to reset the buffer after each line is just an error-prone nuisance. Hence, invent another alternative call pg_get_line_buf, which takes care of that detail. Noted while reviewing a patch from Daniel Gustafsson. Discussion: https://postgr.es/m/48A4FA71-524E-41B9-953A-FD04EF36E2E7@yesql.se
