All Over
(*) Ensure table/column/cursor/... names are always quoted

Build system
(*) Config header templates for various compilers, libpq versions
(*) Completely support building outside the source directory
(*) Ensure there is a way to build without -rpath and use that for the
    Debian packaging.

Connections
(*) Encapsulate definition of prepared statements
(*) Restore prepared statements when restoring a connection
(*) More helpful broken_connection exception hierarchy
(*) Connection pooling support
(*) Support scoped/unscoped non-superuser identity (outside transaction only)
(*) libpqxx-level trace output
(*) Probe, and cache, backend feature set if needed
(*) Speed up connection state restoration by concatenating queries (pipeline?)

Cursors
(*) Older backends don't have NO SCROLL etc.!
(*) Think about positioning and nested transactions
(*) Investigate WITH HOLD feature (nontransaction cursors)
(*) In PostgreSQL 7.4, MOVE and FETCH are much improved (PQcmdTuples()!)

Exceptions
(*) Strip newlines from PostgreSQL error messages in exceptions?
(*) Document exception guarantees (weak / strong / poorly defined / pure)

Large Objects
(*) Support lo_tell()
(*) Check for handling of nul characters

Results
(*) Convert to/from date/time values
(*) Splice out a reusable interface definition
(*) Real encoding support (PQmblen(), PQenv2encoding())
(*) Check for handling of nul characters
(*) Support PQftablecol()
(*) Conceive metadata model
(*) Allow direct mapping onto structs, using member ptr template args

Streams
(*) Permit column list test failures on pre-7.3 postgres backends
(*) Provide metadata information in tablestream
(*) Can we have a tablestream that looks more like a result?
(*) Create "inserter" class for column lists
(*) Allow single-level insertion with endt/endr manipulators
(*) Streambuffer class?

Tests
(*) Test NaN support!
(*) Test tablereader and rows ending in empty fields

Transactions
(*) [pgsql 8.0] Create log table "WITH OIDS" if appropriate
(*) [pgsql 8.0] Support two-phase commit with separate transaction class(es)
(*) [pgsql 8.0] Support nested transactions and savepoints
(*) User schema support for robusttransaction log table
(*) Support SET CONSTRAINTS (no-op for nontransaction).  Make DEFER scoped?
(*) Support constraints definition

Util
(*) Only report closing of non-open sessionfocus during explicit close, not dtor
