I went through PSG a couple of years ago. You can find the results of my
analysis at http://scripts.sil.org/PSGSymbolsVsTUS4. Note that I used
the 2nd edition (you're using the first edition). Also, I haven't
updated this for additions in Unicode 4.1 (maybe I should do that).

In my file above, I indicate character sequences where appropriate.
> Reversed Turned Script A - Mentioned by Kurath (1939), for an
> unrounded low back vowel. "Not in general use", "Extremely rare".
In the 2nd edn, they renamed this Inverted Script A (a more sensible
naming convention).
> Barred B (with a line across the bowl): used by Pike and Smalley for a
> voiced bilabial fricative. "still sometimes found: see e.g. the
> transcriptions in Danesi (1982)." Also seen in Meillet and Cohen
> (1952).
This is a glyph variant of U+0180.
> Barred D: voiced interdental frivative; Pike (1947), Smalley (1963),
> Danesi (1982).
This is a glyph variant of U+0111.
> D with Upper-left Hook (hook attached to top of bowl): Used by Daniel
> Jones to indicate a voiced retroflex stop, esp. Sinhalese. Replaced by
> IPA usage in 1927. See Jones and Laver (1973).
In the 2nd edn, they renamed this Front-Hook D.
> Reversed E (lowercase, not 01DD): Suggested in JIPA 5 for a half-close
> central unrounded vowel. Used by Abercrombie (1967) and Catford
> (1977), Kurath (1939) and Trager (1964).
This is U+0258.
> Barred G (through loop): Pike and Smally for voiced velar fricative.
>
> Crossed G (through descender): Jespersen (1949) and Meillet and Cohen
> (1952) for voiced velar fricative. (=01E5?)
Both of these are glyph variants of U+01E5. (Note that they have never
been used contrastively.)
> Hooktop H with rightward tail: Prokosh (1939) for a voiceless fortis
> velar fricative. "it could simply be a form of italic hooktop _h_ with
> an exaggerated right leg."
In the 2nd edn, they renamed this Right-Tail Hooktop H.
> Heng: Yuen-Ren Chao (1934), used half-seriously for h and eng in
> English phonemics. "Included here [...] because calling it _heng_
> allowed us to devise a name for the otherwise unnameable <hooktop
> heng>)."
I've heard that this was used in one orthography for Tat, but I haven't
seen clear evidence.
> Hooktop Barred Dotless J: Palatal implosive, used by Ladefoged (1971)
> and Maddieson (1984)
This is U+0284.
Re the glyphs that were at one time proposed by one author or another
but not otherwise used, I concluded that these do not need to be
encoded. These would include:
Reversed Turned Script A (Inverted Script A)
A-O Ligature
Inverted Small Capital A
Small Capital A-O Ligature
Slashed D
D with Upper-left Hook (Front-Hook D)
Small Capital Delta
Front- and Back-tailed Gamma
Hooktop H with rightward tail (Right-Tail Hooktop H)
Hooktop J
Barred J
There are others that I might consider candidates for encoding if I
found them in use (though after doing some searching I didn't find
reason to propose them): Slashed B, Barred C, Small Capital F, Heng,
Crossed K .

Why do you hope they're not in Unicode?
