>E.41. Release 8.2.12</A
118
> This release contains a variety of fixes from 8.2.11.
119
For information about new features in the 8.2 major release, see

>E.41.1. Migration to Version 8.2.12</A
134
> A dump/restore is not required for those running 8.2.X.
135
However, if you are upgrading from a version earlier than 8.2.11,
136
see the release notes for 8.2.11.
152
> Improve handling of URLs in <CODE
160
> Improve handling of overlength headlines in <CODE
169
> Prevent possible Assert failure or misconversion if an encoding
170
conversion is created with the wrong conversion function for the
171
specified pair of encodings (Tom, Heikki)
176
> Fix possible Assert failure if a statement executed in PL/pgSQL is
177
rewritten into another kind of statement, for example if an
181
> is rewritten into an <TT
189
> Ensure that a snapshot is available to datatype input functions (Tom)
192
> This primarily affects domains that are declared with <TT
196
constraints involving user-defined stable or immutable functions. Such
197
functions typically fail if no snapshot has been set.
202
> Make it safer for SPI-using functions to be used within datatype I/O;
203
in particular, to be used in domain check constraints (Tom)
208
> Avoid unnecessary locking of small tables in <TT
217
> Fix a problem that made <TT
219
>UPDATE RETURNING tableoid</TT
221
return zero instead of the correct OID (Tom)
226
> Fix planner misestimation of selectivity when transitive equality
227
is applied to an outer-join clause (Tom)
230
> This could result in bad plans for queries like
233
>... from a left join b on a.a1 = b.b1 where a.a1 = 42 ...</TT
239
> Improve optimizer's handling of long <TT
245
> This change avoids wasting large amounts of time on such lists
246
when constraint exclusion is enabled.
251
> Ensure that the contents of a holdable cursor don't depend on the
252
contents of TOAST tables (Tom)
255
> Previously, large field values in a cursor result might be represented
256
as TOAST pointers, which would fail if the referenced table got dropped
257
before the cursor is read, or if the large value is deleted and then
258
vacuumed away. This cannot happen with an ordinary cursor,
259
but it could with a cursor that is held past its creating transaction.
264
> Fix memory leak when a set-returning function is terminated without
265
reading its whole result (Tom)
276
>dblink_get_result(text,bool)</CODE
282
> Fix possible garbage output from <TT
294
> script to properly report failure when
295
unable to obtain linkage information for PL/Perl (Andrew)
300
> Make all documentation reference <TT
307
> as appropriate, instead of the
308
now-decommissioned <TT
320
> Update time zone data files to <SPAN
