After a somewhat long hiatus,
RPostgreSQL version 0.1-7 has now been released to
CRAN. RPostgreSQL
connects R to
PostgreSQL database systems using the standard
DBI interface.

This version fixes a number of issues that had been compiled in the issue tracker on the project site at Google Code. Tomoaki Nishiyama, who joined our small development group for his package a few weeks ago, was instrumental in a number of these fixes, with assistance from Joe Conway.
The relevant NEWS file entry follows below:
Version 0.1-7 -- 2010-10-17
o Several potential buffer overruns were fixed
o dbWriteTable now writes a data.frame to database through a network
connection rather than a temporary file. Note that row_names may be
changed in future releases. Also, passing in filenames instead of
data.frame is not supported at this time.
o When no host is specified, a connection to the PostgreSQL server
is made via UNIX domain socket (just like psql does)
o Table and column names are case sensitive, and identifiers are escaped
or quoted appropriately, so that any form of table/column names can be
created, searched, or removed, including upper-, lower- and mixed-case.
o nullOk in dbColumnInfo has a return value of NA when the column does
not correspond to a column in the table. The utility of nullOk is
doubtful but not removed at this time.
o Correct Windows getpid() declaration (with thanks to Brian D. Ripley)
o A call of as.POSIXct() with a time format string wrongly passed to TZ
has been corrected; this should help with intra-day timestamps (with
thanks to Steve Eick)
o Usage of tmpdir has been improved on similarly to Linux (with thanks
to Robert McGehee)
