185 * There is a bug in the function executor. The backend crashes while trying to
186 * execute an sql function containing an utility command (create, notify, ...).
187 * The bug is part in the planner, which returns a number of plans different
188 * than the number of commands if there are utility commands in the query, and
189 * in part in the function executor which assumes that all commands are normal

202 * The comparison routines for text and char data type give incorrect results
203 * if the input data contains characters greater than 127. As these routines
204 * perform the comparison using signed char variables all character codes
205 * greater than 127 are interpreted as less than 0. These codes are used to

211 * The following flag allows limiting the number of rows returned by a query.

217 * The following flag allows copying tables from files with number of columns
218 * different than the number of attributes setting missing attributes to NULL
219 * and ignoring extra columns. This also avoids the shift of the attributes
220 * of the rest of the file if one line has a wrong column count.
225 * User locks are handled totally on the application side as long term
226 * cooperative locks which extend beyond the normal transaction boundaries.
227 * Their purpose is to indicate to an application that someone is `working'
228 * on an item. Define this flag to enable user locks. You will need the
229 * loadable module user-locks.c to use this feature.
