160 * will wait on a lock before deciding to abort the transaction
161 * (this is what we do in lieu of deadlock detection).

189 * There is a bug in the function executor. The backend crashes while trying to
190 * execute an sql function containing an utility command (create, notify, ...).
191 * The bug is part in the planner, which returns a number of plans different
192 * than the number of commands if there are utility commands in the query, and
193 * in part in the function executor which assumes that all commands are normal
194 * query commands and causes a SIGSEGV trying to execute commands without plan.
196 #define FUNC_UTIL_PATCH
199 * Define this if you want to retrieve arrays attributes as Tcl lists instead
200 * of postgres C-like arrays, for example {{"a1" "a2"} {"b1" "b2"}} instead
201 * of {{"a1","a2"},{"b1","b2"}}.
206 * The comparison routines for text and char data type give incorrect results
207 * if the input data contains characters greater than 127. As these routines
208 * perform the comparison using signed char variables all character codes
209 * greater than 127 are interpreted as less than 0. These codes are used to
210 * encode the iso8859 char sets. Define this flag to correct the problem.
212 #define UNSIGNED_CHAR_TEXT
215 * The following flag allows limiting the number of rows returned by a query.
216 * You will need the loadable module utils.c to use this feature.
221 * The following flag allows copying tables from files with number of columns
222 * different than the number of attributes setting missing attributes to NULL
223 * and ignoring extra columns. This also avoids the shift of the attributes
224 * of the rest of the file if one line has a wrong column count.
229 * User locks are handled totally on the application side as long term
230 * cooperative locks which extend beyond the normal transaction boundaries.
231 * Their purpose is to indicate to an application that someone is `working'
232 * on an item. Define this flag to enable user locks. You will need the
233 * loadable module user-locks.c to use this feature.
