[SQL] Issue with UPDATE statement on v8

[Kenneth Hutchinson]

Hello,   We have recently migrated to Postgres 8 (not sure of exactly which build).  We have noticed that a few functions that were working previously are no longer behaving as expected.  One function in particular is giving me a strange result.   The function giving us the problem is much more complicated, but for simplicity I‘ve included one that is easier to read and results in the same behavior.   UPDATE t_summary SET        availability = 7 WHERE  oid = 28245084   When this query is executed (within a function or without) the database will simply hang.  If the UPDATE is turned into a SELECT, the query works just fine.  For some reason, the UPDATE is just not working.  This same function/query works fines in Postgres 7.2.   The schema for the targeted table is shown below.   CREATE TABLE t_summary (     id                              varchar(20) NULL,     availability                 int4 NULL DEFAULT 0, )   Has anyone else experienced a similar issue?  If more information is needed to determine the problem, please let me know.  I’ve trimmed down the function’s query and table’s schema for this posting.   Thanks in advance!   kh   This message is intended only for the use of the individual(s) or entity to which it is addressed and may contain information that is privileged, confidential, and/or proprietary to RealPage and its affiliated companies.
