I have two type of INSERT queries that keep getting errors no matter how many times I run it in pgadminIII 1.8.4 PostgresQL 8.3.4+PostGIS1.3.5 on centos5 Linux machine.
1. execution of 18MB INSERT queries to one empty table failed in postgis enabled database.sample one of the thousands queries :

INSERT INTO lutons (gid, area, perimeter, map1a_, map1a_id, no_id, no_id2, main, use_bgn, unit, lvls, hght, type_bgn, no_, name_biz, addrss, biz2, code, bgn, code_bgn, builds, note, the_geom) VALUES (1, 1980.087000000000000, 179.134500000000000, 63, 0, '1001001', '1001001', 'Trade', 'Office', 1.000000000000000, NULL, '13', 'one', NULL, 'Wayne Co.', 'Elm Street', 'Office', '836', 'Good', 1, 'm', NULL, '01060000000100000001030000000100000007000000CECAEFA1EEA34BC0F618A264232F69C0BF39315DC29748C01E53771C995369C0B0B8C50181173AC080DEED01F6D16BC0D28922835C2450C08EB4F082865E70C048D67B9E1CDA56C09B5ECFBE2B756DC0AF909ABFC40A4DC04CF2D285506169C0CECAEFA1EEA34BC0F618A264232F69C0');

in the Messages tab console in pgadminIII 1.8.4 prompts this error after 30-60 seconds of executing those queries

ERROR:  geometry contains non-closed rings

Looks like the backslash is interpreted as an escape character. Switch
on 'standard_conforming_strings' and probably turn off
'escape_string_warning'.

Don't know about the other one, I'm guessing you're supplying a
polygon or some other shape that is missing a closing segment (and
thus being a polyline effectively I guess). I've never worked with
shapes in postGIS though.
It could be caused by the above issue if parts of the shape definition
contain backslashes as well.

And finally, I know there is a limit on query size somewhere... You
might be hitting that with 16MB queries.
