## E.316. Release 7.3.6

Release date: 2004-03-02

This release contains a variety of fixes from 7.3.5.

### E.316.1. Migration to Version 7.3.6

A dump/restore is not required for those running 7.3.*.

### E.316.2. Changes

- Revert erroneous changes in rule permissions checking

  A patch applied in 7.3.3 to fix a corner case in rule permissions checks turns out to have disabled rule-related permissions checks in many not-so-corner cases. This would for example allow users to insert into views they weren't supposed to have permission to insert into. We have therefore reverted the 7.3.3 patch. The original bug will be fixed in 8.0.

- Repair incorrect order of operations in GetNewTransactionId()

  This bug could result in failure under out-of-disk-space conditions, including inability to restart even after disk space is freed.

- Ensure configure selects -fno-strict-aliasing even when an external value for CFLAGS is supplied

  On some platforms, building with -fstrict-aliasing causes bugs.

- Make pg_restore handle 64-bit off_t correctly

  This bug prevented proper restoration from archive files exceeding 4 GB.

- Make contrib/dblink not assume that local and remote type OIDs match (Joe)

- Quote connectby()'s start_with argument properly (Joe)

- Don't crash when a rowtype argument to a plpgsql function is NULL

- Avoid generating invalid character encoding sequences in corner cases when planning LIKE operations

- Ensure text_position() cannot scan past end of source string in multibyte cases (Korea PostgreSQL Users' Group)

- Fix index optimization and selectivity estimates for LIKE operations on bytea columns (Joe)
