databases/guile-pg: Update to 0.48

pkgsrc: changes: re-enable .la

There are some test issues, but it seems better to move to 0.48 than
stay at 0.47.  If you are a pkgsrc user of guile-pg and disagree,
please speak up (and help test/fix!).

- 0.48 | 2020-10-26

  - installation by default deletes the .la files

    See README re "SOFIXFLAGS".

  - configuration changes

    - configure script tries to use pkg-config(1)

      The configure script now tries to use pkg-config(1) to determine
      directory values for the ‘-I’ and ‘-L’ compiler switches.  The
      standard way is still supported (see README).

    - configure-time ‘INITDB’ specification

      For "make check", you can specify to the configure script the
      initdb(1) program to use with option ‘INITDB=/path/to/initdb’.
      For example:

       ./configure INITDB=/usr/lib/postgresql/9.4/bin/initdb

      This saves the value of ‘INITDB’ so you don't need to specify it
      manually for each "make check" invocation (see README).

  - builtin array variant types now have prefix-asterisk names

    Previously, the builtin array variant types had names that end
    in "[]" (i.e., one or more pairs of square braces).  These now
    have prefix-asterisk names.

     (was)              (now)
     text[]             *text
     text[][]           **text
     int4[]             *int4
     aclitem[]          *aclitem

    Furthermore, old-style names are no longer supported.  This is
    concomitant w/ dropping of ‘define-db-col-type-array-variant’
    (see below).

  - dropped items

    All these were announced in Guile-PG 0.47 (2015-02-23).

    - module ‘(database postgres-resdisp)’

    - proc ‘(database postgres) pg-lo-read’

    - procs in module ‘(database postgres-types)’

      - ‘dbcoltypes’

      - ‘dbcoltype-lookup’

      - ‘dbcoltype:stringifier’

      - ‘dbcoltype:default’

      - ‘dbcoltype:objectifier’

      - ‘define-db-col-type-array-variant’
