release notes:

  Woo hoo, "half"-way there!  :-D

  Let's hope we can reach 1.0 sometime this decade...

  Also, hackers may want to check out the Git repo, new dir xp/,
  for yet another way to push your multicore system to insanity.

README excerpt:

  Guile-PG is a collection of modules for Guile allowing access to
  the PostgreSQL RDBMS from Scheme programs.

  The low-level module ‘(database postgres)’ provides an almost
  one-to-one correspondence with the PostgreSQL "libpq" C library
  interface.  The other modules build on it to provide abstractions
  and convenience procedures.

NEWS for 0.50 (2021-12-04):

  - distribution now .tar.lz

    If you have GNU tar, you can use "tar xf" and it will DTRT.
    If not, you can use "lzip -dc TARBALL | tar xf -" to unpack it.

  - lob details bifurcated for "modern" Guile

    Guile 2.2 (and later, presumably) have ‘scm_c_make_port’ and in
    fact a whole rewrite of the ports extension mechanism.  Thus,
    all previous Guile-PG releases failed to build w/ Guile 2.2.
    Specifically, all the large object (lob) low-level details
    clashed irreconcilably.

    This release of Guile-PG now handles things by configure-time
    detection and selection of a suitably matching implementation.

    The file test/OK now includes an entry w/ a subheading of "other
    Guile" to show the range of supported Guile versions.  More to
    the point, if you build w/ Guile 2.2 and encounter problems,
    then please report it.

    NB: We haven't dipped into the Guile 3.0 waters yet.  Experience
    reports from those more adventurous are welcome, in any case.
