Timothy, I just ran gdal_contour (from gdal-1.10.1) on http://dds.cr.usgs.gov/srtm/version2_1/SRTM1/Region_01/N38W114.hgt.zip with the options -i 10 and -a height. I got a shape file of ~95MB. Please check your data file and gdal version.
BTW, you can directly save the contours into a postgis table instead of the intermediate shapefiles by using the -f option.
